A fan is listed having the  following performance with standard air: Volume discharge : 120m3 /s Speed : 7.0rps Static Pressure : 310mm water gage BP Required : 620kW The system duct will remain the same and  the fan will discharge the same volume of  120m3 /s of air at 93o C and a barometric  pressure of 735mm of Hg, when its speed is  7.0rps. Find the brake power input of the fan  and the static pressure required.   Provide solutions and schematic diagram.

Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.
