A stream of outdoor air is mixed with a stream of return air in an air-conditioning system that operated at 101.325 kPa barometric pressure. The flow rate of outdoor air is 2.0 kg/s, and its condition is 35℃ DB and 25℃ WB temperatures. The flow rate of return air is 3.0 kg/s, and its condition is 24℃ DB and 50% RH. If the ambient pressure is 98 kPaa, determine the following:a. The enthalpy of the mixture in kJ/kg dry-airb. The humidity ratio of the mixture in kg/kg dry-airc. The dry-bulb temperature of the mixture in ℃.

Question

A stream of outdoor air is mixed with a stream of return air in an air-conditioning system that operated at 101.325 kPa barometric pressure. The flow rate of outdoor air is 2.0 kg/s, and its condition is 35℃ DB and 25℃ WB temperatures. The flow rate of return air is 3.0 kg/s, and its condition is 24℃ DB and 50% RH. If the ambient pressure is 98 kPaa, determine the following:

a. The enthalpy of the mixture in kJ/kg dry-air

b. The humidity ratio of the mixture in kg/kg dry-air

c. The dry-bulb temperature of the mixture in ℃.
