Steam flows through a turbine at the rate of 100 lb/min with ∆KE = 0 and Q = 0. At entry, its pressure is 175 psia, its volume is 3.16 ft3/lb, and its internal energy is 1166.7 Btu/lb. At exit, its pressure is 0.813 psia, its volume is 328 ft3/lb, and its internal energy is 854.6 Btu/lb. What horsepower is developed? (b) The same as (a) except that the heat loss from the turbine is 10 Btu/lb of steam.

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.
