Pumps are devices used to move fluids from one place to another. There are various types of pumps based on their working principle and application.

• Centrifugal pumps: use rotating impeller to increase fluid velocity and pressure

• Reciprocating pumps: use piston or diaphragm to create pressure

• Gear pumps: use interlocking gears to move fluid

• Peristaltic pumps: use rollers to squeeze fluid through a tube

• Diaphragm pumps: use f

Cooling towers are used to remove heat from a building or industrial process by transferring it to the atmosphere.

• Cooling towers are commonly used in HVAC systems, power plants, and manufacturing processes.

• They work by evaporating a small amount of water to remove heat from the rest of the water circulating through the system.

• The cooled water is then recirculated back into the system to absorb more heat.

Ohm's Law states that the voltage (V) in a circuit is equal to the current (I) multiplied by the resistance (R).

• V = I * R

• Voltage is measured in volts (V)

• Current is measured in amperes (A)

• Resistance is measured in ohms (Ω)

• Example: If a circuit has a current of 2A flowing through a resistance of 5Ω, the voltage would be 10V (2A * 5Ω = 10V)
