Using the Science of Drones for Investigating

Crescent Investigations, LLC says that in the recent years, the use of drones by private investigators has increased. This is after a ruling by a judge to lift the ban on the use of commercial drones. With that said, there are ways in which a private investigator uses drones for work. Here are four of these ways.

• Using drones to locate hidden items on people’s backyards, which is almost the same as law enforcement using helicopters to search marijuana fields.

• In accident reconstructions, private investigators and law enforcement can use drones to document events as they happen.

• Drones can be used to show real-time imagery, and when used with Google Earth, they can show clear evidence of how topology has changed over time.

• Private investigators can also use drones for surveillance instead of going to a suspect’s home in person. Using drones minimizes the chances of being shot or being accused of trespassing.

With the use of drones, it becomes easy for private investigators to provide information required by insurance companies, attorneys, and government officials.

The Science of How an Air Conditioner Works!

How does an air conditioner work?

To be more precise, these machines operates in a similar manner just as the refrigerators. Instead of cooling just a small insulated area inside of the refrigerators, an air conditioner cools an entire room or a whole house.

Air conditioners use chemicals which regularly reverses itself from a gaseous state to a liquid state. These particular chemical transfers heat from the air inside your the house or a home to the air outside.

The central cooling system consists of three distinct parts, including the evaporator, the compressor, and a condenser. The evaporator is located inside the house, usually in the context of the furnace. It is the part which heats the house of yours. The condenser and the compressor are often located on the outside air part of the conditioner.

The working liquid reaches the compressor as an entirely low-pressure and a cooling gas. The compressor then squeezes this particular fluid. Scientifically, this process is aimed at packing the fluid’s molecules closely together. When the particles are firmly packed, its temperature and the energy increases significantly.

The working liquid then exits the compressor as a boiling gas with high pressure, as it flows slowly into the condenser. This working fluid then leaves the condenser as a liquid and is also much cooler since it was subjected to high pressures. It then enters the evaporator via a subtle hole which is narrow. On the other side, the pressure of the liquid drastically drops, and it starts evaporating again into a gas.

As the fluid changes to gaseous state, it extracts the heat from the air around as it evaporates. The heat in the air is vital in mobilizing the molecules of the fluid as they change from liquid to gas. It is also important to note that the evaporator is equipped with metal fins, which ensures an efficient exchange of thermal energy with the surrounding air. At the time when the working liquid comes out of the evaporator, it is a very cool and a gas of low pressure. For the continuity of the process, it goes back to the compressor to start the trip once again.

There is a fan which is connected to the evaporator. Its function is to circulate the air inside the house and make them blow across the fins of the evaporator. Bearing in mind that warm air is lighter than cold air, the hot air inside the room rises to the top. There is a vent there, by which the air goes inside the air conditioner, traveling through the ducts. The hot air is used in cooling the gas inside the evaporator. As the heat is being eliminated from the air, it undergoes cooling and then blown into your house via other ducts, which are often located at the level of the floor.

The process is repeated over and over, until your room the reaches your preferred temperature level. The thermostat somehow detects that the temperature has come to the intended setting, and therefore it automatically turns the air conditioner off.

The science of air conditioning – for cooling your home.

If you are struggling to live a comfortable and pleasurable life in hot summer months then air conditioning is the best option for you as it helps you to deal with the heat and dampness of summer in an efficient manner. The air conditioner is one of the most important home appliances that help in eliminating the unwanted heat from your room and thus it is important to know the science of air conditioning so you can hire a company like Alpha Air, LLC that can install it properly!

Air conditioners make use of refrigeration for chilling the indoor air so that you can have a comfortable environment inside your room. It also provides you an opportunity of relaxing within the confines of your room and the science of air conditioning is that the appliance takes advantage of the physical law. The liquid inside the air conditioner converts to the gas with the process known as phase conversion and it eventually helps in absorbing the heat from the environment. This appliance exploits the most important feature of phase conversion as it forces the special chemical compounds for evaporating and condensing over and over again in closed system of coils. The compounds that are involved in this process are known as refrigerants that have different properties that enable them to be changed at relatively low temperatures. The air conditioning unit also compromises of fans that move the warm interior air these cold and refrigerant filled coils. These air conditioners have whole system of ducts that are especially designed to funnel the air to and from the serpentine and air chilling coils.

The science of air conditioning is the use of cooling technology that is used for cooling the air inside the room and it also make use of the blowers that helps in pulling the heat and moisture from room air to filter. The air is then dehumidified by the blowers which are then blown back into the room and thus the air conditioner needs to have an opening so that the hot air is pushed outside from the room. The air conditioners are energy efficient as it consumes energy that is required for cooling the room rather than consuming a large amount of energy for cooling the whole building or house. It provides comfort cooling to the room where it is installed and it also helps in preventing appliances like computer from overheating and hence eliminates the risk of damage.  If you want to read more about how air conditioning work you check out more about Alpha Air, LLC because they offer some of the very best air conditioning baton rouge has to offer the surrounding areas!

What Is The Science Behind Home Electrical Systems?


Electricity refers to a form of energy that results from the existence of charged particles. These particles, such as protons and electrons may either exist in a static state as a result of accumulation of charge or dynamically as a result of the flow of current.

Electricity as a form of energy has many uses including supplying energy to industrial plants as well as residential homes. In this article we shall look at the exact process that entails the flow of electricity from the production plants to your home. Join me, therefore as we look into the science of home electrical systems.

At The Plants

The electricity production plants generate electricity through steam that results from the combustion of fossil fuels or at a hydroelectric or nuclear plant.

Once generated, this steam powers a turbine and the turbine spins a huge magnet that’s inside a copper wire. As a result, the heat energy generated transforms into mechanical energy before converting into electrical energy.

From the Plant to Your Home

Once generated, electricity flows from the plant through wires that are intermittently connected by a chain of transformers hung on electrical poles.

The sole purpose of these transformers is to raise the pressure of the electricity so that it can travel over long distances and finally reach your home, especially if you are located far away from the production plants. The pressure can be raised to 756 000 volts.

The current is then run through power lines to a substation transformer where pressure is further lowered to between 2000 & 13000 volts.

From the substations, electricity is taken through various lines to a pole transformer or a transformer box in case of underground connections. At this point, pressure is lowered further to between 120 & 240 volts.

From the Transformer To Your Power Control Panel

From the transformer, electricity travels to your home power control panel. This is usually a cabinet which contains a system of electrical wires as well as electrical components needed to control the motors and equipment. Depending on the size of your house, the panel could be located inside the house or in a specially designed shed outside.

Aside from housing the electrical components, the power control panel protects the contents from electrical wires from harsh weather, especially rain and storms that could trigger massive failures in the system.

Movement Within Your Home

It is important to note that not all homes have the Power Control Panels and in such cases, electricity is passed directly from the pole transformer to the meter box. The meter box is used to measure the number of units of electrical energy used in your home. These units are measured in kWh.

From the meter box, electricity will go through the main switch. The main switch plays vital roles as it can be sued to cut off the supply of electricity altogether, either for repair and maintenance needs or simply as a measure of caution.

Movement to Lighting and other Appliances

For electricity to flow to a light or an appliance, a path is provided through which it can also return to the generator. This path forms the circuit. The path must be made up of at least two wires namely the active or live wire that takes electricity away from the generator and to your home appliances and the neutral wire that takes the electricity away from your home appliances back to the generator. This explains why each appliance must have at least two wires.

Additionally, a large number of electrical outlets, also referred to as power points, need to be included in your home as these not only reduce the risk of overloading but also eliminate the excessive use of double adaptors and extension cords.

Risk-control measures

Last but not least, an efficient electrical system in your house should contain a fuse board. The board contain fuses that act as safety valves that protect the wires as well as the occupants of the house. In order to ensure that you and your appliances are safe, the fuse acts as a safety device and detects any extra loads beyond the amount it was designed to carry. This load will cause it to melt and low up, thereby disconnecting the devise from electrical supply and ultimately ensuring its and your safety.
