Hydrogen enters the turbine of an Ericsson cycle at 1040 K, 5 bar with a mass flow rate of 1 kg/s. At the inlet to the compressor the condition is 300 K and 1.5 bar. Assuming the ideal gas model and ignoring kinetic and potential energy effects, determine:
a. the net power developed, in KW.
b. the thermal efficiency.
c. the back work ratio.

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.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
