Afossil-fired power plant uses an ideal saturated rankine cycle with a steam flow rate of 6500 lbm/hr. the boiler pressure is 1500 psia; and the condenser pressure is 2 psia. the plant capacity factor is 80%. determine: (a) the feedwater pump specific work, (b) the net power output (in kw or mw) of the cycle, and (c) the plant thermodynamic efficiency.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges
