Due: February 22, 2008 MAE 112 Homework Assignment #5 1. Consider one-stage of a compressor with a 10% static pressure rise across the rotor followed by another 10% pressure rise across the stator (compounded to be 21%). The incoming flow has a velocity of 100 ft/sec in the axial direction, a temperature of 700 ° R and a pressure of two atmospheres. γ = 1.4 and c p = 0.24 Btu/1bm. Assume a polytropic efficiency of 0.97 for the compressor stage. What is the power per unit mass flow of the compressor? If the rotor blade speed averages 1000 ft/sec, what is the tangential component of velocity exiting the rotor? 2. Consider a turbine stage that has a polytropic efficiency of 0.96 for the stator (nozzle) and for the rotor flow. None of the total static enthalpy drop through the stage occurs in the rotor portion. The initial and final velocities for the stage are axial and have no swirl (tangential component). Assume that only the tangential component of velocity changes through the stator (nozzle) portion. The flow has
