Aerospace Engineering > GATE 2021 > Axial Turbines
A single-stage axial turbine has a mean blade speed of 340 m/s at the design condition with blade angles at the inlet and exit of the rotor being 21° and 55° respectively. The degree of reaction at the mean radius of the rotor is equal to 0.4. The annulus area at the rotor inlet is 0.08 m2 and the density of gas at the rotor inlet is 0.9 kg/m3. The flow rate through the turbine at these conditions is _______ kg/s. (round off to two decimal places)
Correct : 18.0 to 19.5
