Q$2.$ The velocity of steam leaving the nozzle of an impulse turbine is $800\frac{m}{s}$ and the nozzle

angle is $20.$ The blade velocity is $200\frac{m}{s}$ and the blade velocity coefficient is $0\mathrm{.}80.$ Assuming

no loss due to shock at inlet, calculate for a mass flow rate of $0\mathrm{.}5k\frac{g}{s}$ and symmetrical blading

A$.$ Blade inlet angle.

B$.$ Driving force of the wheel.

C$.$ Axial thrust on the wheel and

D$.$ Power developed by the turbine.
