Steam enters a well-insulated turbine at 500 bar and 600oC with a velocity of 100 m/s. The stream exits the turbine at 5 bar and 225oC with a velocity of 200 m/s. The turbine produces 32.5 MW of power. Calculate the steam mass flow rate (kg/s) through the turbine and the diameter (m) of the exit line assuming it is a cylindrical pipe.

Write short note on the following ; collision theory, rotation angle and angular velocity, centripetal acceleration, coriolis force, and newton's law of gravitation.
