Multiple choice

Moist air at a pressure of 100 kPa is compressed to 500 kPa and then cooled to 350C in an after cooler. The air at the entry to the after cooler is unsaturated and becomes just saturated at the exit of the after cooler. The saturation pressure of water at 350C is 5.628 kPa. The partial pressure of water vapour (in kPa) in the moist air entering the compressor is closet to
