Extracted text: 3.25 The rotational speed of a reaction turbine is 200 rpm and the inlet and outlet diameters are 10 ft. and 3 ft., respectively. The inlet absolute velocity has a radial component of 25 ft./s and tangential component of 45 ft./s. At the outlet, the fluid is directed radially and has a magnitude of 50 ft./s. Calculate (a) degree of reaction, (b) utilization factor. If the exit velocity is 51.4 ft./s, calculate (c) the degree of reaction. Ans: R=98.4%; ɛ=0.792; R=100% (almost)
