The material hoist and the load have a total mass of 900 kg and the counterweight C has a mass of 150 kg. At a given instant, the hoist has an upward velocity of 4 m/s and an acceleration of 1.2 m/s^2. Determine the power generated by the motor M at this instant if it operates with an efficiency of epsilon = 0.8.
Air enters a turbine at 40 kN/m2, 900 C, and leaves at 10 kN/m2. The flow is reversible and adiabatic. Inlet velocity is quite low and outlet velocity is 150 m/s through a cross-sectional area of 0.20 m2. Calculate the power output in kW.
