Q1. 1. The steam supply to an impulse turbine with a single row of moving blades is 2 kg/s. the turbine developed 130 kW, the blade velocity being 175 m/s. the steam flows from a nozzle with a velocity of 400 m/s and the velocity of coefficient of blade is 0.9. Find the nozzle angle, blade angle at inlet and exit, if the steam flows axially after passing over the blades. [Hint: For axial flow at exit =90]
