Calculating sensible heat, latent heat, and heat of vaporization of water

A 1000 m3/min air flow at 170 degrees F and containing 60% relative humidity needs to be cooled to 48 degrees F to promote condensation of the water vapor in the air. How would you calculate the sensible heat, the latent heat, and determine the latent heat of vaporization of the water vapor in this air stream as the air is cooled from 170 F to 48 F??

A 1000 m3/minute air stream at atmospheric pressure is at a temperature of 82.2oC

A 1000 m3/minute air stream at atmospheric pressure is at a temperature of 82.2oC and a humidity of 60%. We want to cool the air + water vapor to 8.9oC to condense the water vapor. Determine the sensible cooling and latent cooling required to drop the temperature of the air mass from 82.2oC to 8.9oC and condense the water vapor. Determine both the sensible and latent cooling requirements in units of KW and BTU/sec?

Ideal vapor compression refrigeration cycle with counter-flow heat exchanger.

Refrigerant 134a leaves the evaporator as saturated vapor at 1.4bar and is heated at constant pressure to 20 degrees C before entering the compressor. After isentropic compression to 12bar, the refrigerant passes through the condensor exiting at at 44 degrees C, 12 bar. The liquid then passes through the heat exchanger, entering the expansion valve at 12bar. The mass flow rate of refrigerant is 6 kg/min, determine: a. coefficient of performance b. compressor power input

Temperature in the Tank

A rigid tank contains 5 kg of an ideal gas at atm and 40° C. Now valve is open, and half of mass of the gas is allowed to escape. If the final pressure in the tank is 1.5 atm, what is the final temperature in the tank?

Determine Compressor Size in Watts that is suitable to satisfy certain specific needs

The drinking water needs in a production facility with 20 employees is to be met by a water bubbler type water fountain. The system is to cool water from 22C to 8C and supply cold water at a rate of .4L per hour per person. The reservoir is not isolated and an additional heat load at a rate of 45 W coming from the surrounding air is to be considered on the refrigeration system. If the COP of the refrigeration system is 2.9, determine the size of the compressor, in Watts, that will be suitable to satisfy the cold-water needs in the production facility.
