Homework 2 Solutions1
Problem 1: Lumleys book provides a rough value of 0.69 for o /ac at =1. Could you provide a
simple explanation for this rather large degradation in efficiency when properties of real gases are
considered. I am looking for a heuristic
Solutions to Homework 5
Problem 1
The shaft of small turbine turns at 20000 rpm, and the blade speed is U = 250 m/s. The axial
velocity leaving the stator is Vx2 = 175 m/s. The angle at which the absolute velocity leaves
the stator blades is a2 = 67, the
