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.

Steam enters a turbine with an enthalpy of 3300 KJ/kg and leaves with an enthalpy of 2400 kJ/kg. The power output of the steam turbine is 6 MW Determine the change in enthalpy per unit mass.  Determine the change in kinetic energy per unit mass.  Determine the change in potential energy, Determine the work done per unit mass of the steam flowing through the turbine. Calculate the mass flow Rate of the steam.

In turbochargers a turbine is directly connected to a compressor. The power harvested by the turbine is used to power the compressor. In the figure below a turbine runs on steam and powers a compressor on air. Air can be considered a perfect gas with k = 1.34, R = 0.28 kJ/kgk and cp = 1.02 kJ/kgK. The air enters the compressor at p₁ 1bar, T₁ = 300K and a mass flow rate of mdot = 5.9 kg/s and exits at p2 5.2 bars. The steam enters the isentropic turbine at P3 = 2 MPa, T3 = 320°C and exits at p4 = 100 kPa. = = State 2 Isentropic Compressor State 1 Air-perfect gas T₁ = 300K P₁= 1 bar Answer: W tubine = ? State 4 Isentropic Turbine State 3 Steam T3=320°C P3= 2MPa What is the mass flow rate of steam through the turbine? Please enter your answer in kg/s

Air (R = 0.3074 psia.cf/lbm.R) is compressed from 14.7 psia and 60°F to a pressure of 150 psia while heat loss rate during the steady compression is 10 Btu/lbm. The volume flow rate of the air at the inlet is 5,000 ft'/min and the power input to the compressor is 700 hp. Determine the temperature at the compressor exit in °F. (1hp = 0.7068 Btu/s) AIR %3D 10 Bru Ibm
