10. 66 A single-stage axial flow gas turbine is to be tested in a "cold rig" so as to simulate the design-point operation. The two sets of operating conditions are: 1. Design-point operation of turbine Stage inlet total pressure, Poi = 11 bar Stage inlet total temperature, To1 = 1400 K Stage-exit total pressure, P02 5.0 bar = CHAPTER 2 Dimensional Analysis: Similitude Speed of rotation, N= 55,000 rpm Stage efficiency, t = 87% Mass flow rate m = 3.5 kg/s 2. Cold-rig operation Stage inlet total pressure, P01(cr) = 2.5 bar Stage-inlet total temperature, Tol(cr) 365 K For both sets of conditions, assume that the axial velocity across the stage remains constant. Determine - a. the stage-exit total temperature To2(cr); b. the power output in the cold rig. Assume that the average specific heat ratio for both operating conditions is given by Y = 1.36.

8.4 The later stages in an axial flow turbine are reaction-type stages. In one such stage, the degree of reaction is 50%. The mean radius and height of the rotor blades are 3 in. and 1 in., respectively. The speed is 40,000 rpm and the flow coefficient þ=0.24. The rotor exhaust temperature and pressure are 60°F and 14.7 psia, respectively. If V12 = 1100 ft./s, calculate the following: (a) nozzle angle, (b) blade loading coef- ficient, (c) total temperature at the stage inlet and exit, and (d) power.
