Problem no 1
Air flow through an air turbine rotor where the stagnation pressure drops at a rate 5:1 total to efficiency is 0.8 and the air flow rate is 5 km2sec if total power output is y = 1.4 and cp= 1004 j2kgk find; i) inlet total temperature ii) Actual exit total temperature if exit velocity is 100m/sec and total to static efficiency of the rotor
