Q$1.1.$ The steam supply to an impulse turbine with a single row of moving blades is $2k\frac{g}{s}.$

the turbine developed $130kW,$ the blade velocity being $175\frac{m}{s}.$ the steam flows from a nozzle

with a velocity of $400\frac{m}{s}$ and the velocity of coefficient of blade is $0\mathrm{.}9.$ 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 $=90]$ power plant
