A1.5 m3 tank contains 500 kg of liquid water in equilibrium with pure water vapor, which fills the remainder of the tank. the temperature and pressure are 100°c and 101.33 kpa. from a water line at a constant temperature of 70°c and a constant pres- sure somewhat above 101.33 kpa, 750 kg of liquid is bled into the tank. if the temper- ature and pressure in the tank are not to change as a result of the process, how much energy as heat must be transferred to the tank?

Asher cycles 12 miles in 16 hours. what is his speed?

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
