Abaseball pitcher throws the ball in a motion where there is rotation of the forearm about the elbow joint as well as other movements. if the linear velocity of the ball relative to the elbow joint is 22 m/s at a distance of 0.416 m from the joint and the moment of inertia of the forearm is 0.524 kg m2 , what is the rotational kinetic energy of the forearm?

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
