As the air goes through the compressor of a gas turbine engine, it undergoes an increase in pressure such that the pressure ratio at the compressor exit to the compressor inlet is 15 (Note this is aratio and not a difference). What is the ratio of exit to inlet density, given the bulk modulus of air is 101000 N/m2
