A well-insulated turbine operating at steady state develops 30 MW of power for a steam flow rate of 50 kg/s. The steam enters at 30 bar with a velocity of 80 m/s and exits as saturated vapor at 0.08 bar with a velocity of 150 m/s. Neglecting potential energy effects. Determine the inlet temperature, in ∘C.

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.
