Question

The air in a building is to be maintained at 25°C and 55% relative humidity by passing outside air through a water spray. The air enters the spray chamber at 32°C and 70% relative humidity, leaves the chamber cooled and saturated with water vapor, and is then reheated to 25°C. Estimate the temperature of the air (in °C) leaving the spray chamber. Round the answer to one decimal place.

Step 1

Given: Relative humidity = 55% Vapour pressure of water at 25°C = 23.756 mmHg Barometric pressure = 760 mmHg Mole fraction of water in the outlet air, y1 = 0.55 * 23.756 / 760 y1 = 0.0172 Show more…
