Condensers are used in power plants to convert steam back into water for reuse in the boiler.

• Condensers increase the efficiency of the power plant by allowing the reuse of water.

• They reduce the amount of water needed for the power plant.

• Condensers also help to maintain a vacuum in the turbine exhaust, which increases the power output.

• Examples of condensers used in power plants include surface condensers and jet condens

CFM of blower can be calculated by multiplying the blower's airflow rate by the blower's operating speed.

• Determine the airflow rate of the blower in cubic feet per minute (CFM)

• Determine the operating speed of the blower in revolutions per minute (RPM)

• Multiply the airflow rate by the operating speed to get the CFM of the blower

• CFM = Airflow rate (CFM) x Operating speed (RPM)

Heat transfer is the movement of thermal energy from one object to another. There are three modes of heat transfer: conduction, convection, and radiation.

• Conduction is the transfer of heat through a material without any movement of the material itself. Example: Touching a hot stove.

• Convection is the transfer of heat through the movement of fluids (liquids or gases). Example: Boiling water.

• Radiation is the transfer of h...read more
