Question 102
XE-ENAT2 marksNeeds review
Air at 101 kPa, 15 °C and 50% relative humidity is first heated to 20 °C in a heating coil, and then humidified by spraying water on it. In the final state, the air has temperature of 25 °C and relative humidity of 85%. The amount of water sprayed (in gm per kg of dry air is _________________ (rounded off to two decimal places).
Use the following data:
The saturation pressure of water at 15 °C = 1.7057 kPa
The saturation pressure of water at 25 °C = 3.1698 kPa
