Estimate the stagnation temperature of the compressed air at the outlet of the diffuser T03 in oC. The compressor is operating at 21,212 rpm and the impeller has outlet diameter of 268mm. The total pressure at the outlet of the impeller P02 is 442.5kPa and the stagnation temperature of the air at the outlet of the impeller T02 is 128.1oC. Assume the specific heat capacity of air cp = 1006 J/kg.K and cv = 718 J/kg.K. Also assume there are no energy losses in the diffuser
