Water is the working fluid in a rankine cycle. steam enters the turbine at 150 kpa and 200°c. the condenser pressure is 20 kpa. both the turbine and pump have isentropic efficiencies of 80%. the working fluid has a negligible pressure drop in passing through the boiler. the net power output is 1×109 w. the cooling water experiences a temperature increase from 20°c to 35°c with negligible pressure drop as it passes through the condenser. determine for the cycle: (a) the mass flow rate of steam in [kg/hr (b) the rate of heat transfer in [kj/hr] to the working fluid passing through the steam generator (c) the thermal efficiency (d) the mass flow rate of cooling water in [kg/hr] answer) (a) 12805e7 kg/hr; (b) 3.3567e 10 kj/hr; (c) 10.7%; (d) 4.777& e8 kg/hr turbine 慚 cooling water pump condenser wi

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.
