Question 2

The minimum temperature upto which the water can be cooled in a cooling tower is

Question 3

A moist air sample has dry bulb temperature of 30 °C and specific humidity of 11.5 g water vapour per kg dry air. Assume molecular weight of air as 28.93. If the saturation vapour pressure of water at 30 °C is 5.24 kPa and the total pressure is 90 kPa, then the relative humidity (in %) of air sample is
