Laboratory angular momentum purpose to investigate conservation of angular momentum by indirectly measuring the moments of inertia and directly measuring the angular velocities for initial and final configurations of a system.
1. as a the square mass is moved closer to the axis of the rotation, will the angular velocity of the rotating platform increase, decrease, or remain the same?
2. what will be the angle between the tension force in the string and the radius (lever arm) of the spindle in part ii?
3. derive a formula for the moment of inertia you will calculate in part ii in terms of the quantities you will measure in this lab.

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.
