An IFR turbine with flat blades rotates at 20,000 rpm. The radii at the inlet and mean outlet are 8 in. and 4 in., respectively. If the static conditions at the exit are 14.7 psia and 800°F, calculate the fluid angle (@) at the exit and the mass flow rate. The power produced is 140 hp and the blade width (height) is 3 in. at both the inlet and exit. Ans: 81.6°; 1.7 lbm/s
