35) When the temperature of air leaving the intercooler, in a two stage compression with intercooler, is __________ the original atmospheric air temperature, then the intercooling is known as perfect or complete intercooling.

36) The actual volume of air delivered by a compressor, When reduced to the normal temperature and pressure conditions is called compressor capacity.

37) The compression ratio in a gas turbine is

38) Intercooling in compressors results in saving of power in compressing given volume of air to a given pressure.

39) Only rocket engines can be propelled to space because
