Arigid, sealed container of r134a initially at -30°c and 40% quality is placed inside a room so that it heats up at 5°c/hr. if there is 3 kg of r134a in the container, determine: a) the volume of the container b) the specific volume of the vapour when the r134a finishes converting into a gas c) the pressure when all the r134a has finished converting into a gas d) the energy required to turn all the r134a into a gas e) how long it will take for all the r134a to become a gas

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
