The by-pass factor, in case of sensible cooling of air, is given by (where t_d1 = Dry bulb temperature of air entering the cooling coil, t_d2 = Dry bulb temperature of air leaving the cooling coil, and t_d3 = Dry bulb temperature of the cooling coil)

If the evaporator temperature is kept constant, the coefficient of performance of a refrigeration cycle __________ with the increase in condenser temperature.

In a psychrometric chart, dew point temperature lines are horizontal and non-uniformly spaced.

The highest temperature during the cycle in a vapour compression system occurs after evaporation.

A simple air cooling system is good for __________ flight speeds.
