Aproposal is to build a 1000-mw electric power plant with steam as the working fluid. the condensers are to be cooled with river water. the maximum steam temperature is 550 celsius, and the pressure in the condensers will be 10 kpa. the river is 60 m wide and 8 m deep, and flows at a velocity of 10 m/min. estimate the temperature rise of the river downstream from the power plant.

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.
