Q$3.$ A steam jet enters the row blades with a velocity of $600\frac{m}{s}$ at an angle of $25$ with the

direction of motion of the blades. If the blade speed is $250\frac{m}{s},$ find the suitable inlet and outlet

blade angles assuming that there is no thrust on the wheel. The velocity of steam passing

through the blades is reduced by $20\%.$ Also, determine the power developed by the turbine per

$kg$ of steam flowing over the turbine per second.
