Carbon dioxide (CO2) gas undergoes a process in a closed system from T1 5 1008F, p1 5 20 lbf/in.2 to T2 5 4008R, p2 5 50 lbf/in.2 The entropy produced due to internal irreversibilities during the process is determined to be 0.15 Btu/8R per lb of gas. The carbon dioxide can be modeled as an ideal gas. Determine if the energy transfer by heat, Q, is positive (into the system), negative (out of the system), or zero.

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.
