Aclosed, rigid tank contains a two-phase liquid-vapor mixture of refrigerant 22 initially at-20°c with a quality of 52.50%. energy transfer by heat into the tank occurs until the refrigerant is at a final pressure of 6 bar determine the final temperature, in °c if the final state is in the superheated vapor region, at what temperature, in oc, does the tank contain only saturated vapor?

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.
