Open questionXE-ENAT2 marksNeeds review
A stream of moist air enters an adiabatic saturator at 45 °C and 101 kPa and leaves as a saturated mixture at 30 °C. Make-up water to the saturator is supplied at 30 °C. The amount of make-up water (in grams per kg of dry air) supplied is __________ (rounded off to two decimal places).
Use the following data:
Specific heat capacity of water is 4.2 kJ/kg-K
Specific heat capacity of air at constant pressure is 1 kJ/kg-K
Saturated water properties:
At 30 °C: specific enthalpy of saturated water vapor is 2556 kJ/kg-K, specific enthalpy of saturated liquid water is 125.7 kJ/kg-K, and saturation pressure is 4.25 kPa
At 45 °C: specific enthalpy of saturated water vapor is 2582 kJ/kg-K, specific enthalpy of saturated liquid water is 188.4 kJ/kg-K, and saturation pressure is 9.60 kPa
