A turboprop engine consist of a diffuser, compresser, combaster, turbine and nozzle. the turbine druves a propeller as well as the compressor. air enters the diffuser with a volumetric flow rate of 83.7m3 /s at 40KPa, 240K and a velocity of 180m/s, and decelerate essentially to zero velocity.the compressor ratio is 10 and the compressor has an isentropic efficiency is 85%.the tuebine inlet temperature id 1140K, and it's isentropic efficiency is 85%. the turbine exit pressure is 50kPa. flow through the diffuser and the nozzle is isentropic. sketch the process on the T-s diagram and using an air standard analysis, determine i. the power delivered to the propeller, in MW ii. the velocity at the nozzle exit, in m/s
