At 60°F, freon-12 (dichlorodifluoromethane) has a vapor pressure of 72.4 pounds per square inch (1.0 atm = 14.7 psi). If I opened a pressure vessel containing liquid freon-12 and poured it into an open beaker in the lab how much liquid freon would remain when equilibrium is established? Explain.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
