A gas initially at 1.5 bar pressure, 0.15m
3
volume and 300 K was compressed
polytropically (pv 1.25 = constant) to 15 bar pressure. Determine the change
in entropy. Also work out the approximate entropy change obtained by
dividing the heat transferred by the mean absolute temperature during compression.
Take cp = 1.04 kJ / kg K and cv = 0.745 kJ / kg K.

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.
