Problem 2: A turbine accepts steam at 3000kPa and 800 °C and leaves at 100 kPa with a quality of 30%. If the Criss flow rate is 5 he's determine the power puput. (Neelect kinetic & potential energy changes. Neglect heat kg/s

8.5kg/s of of air are compressed isothermally from 90kPa 8m3/s to 600kPa. If the Initial and final velocity of the gas is 15m/s and 50m/s with negligible changes in potential energy, Find the Work steady flow(kW)

A steam turbine has an inlet of 2 kg/s water at 1000 kPa, 350 °C and velocity of 15 m/s. The exit is at 100 kPa, 150 °C and very low velocity (assume zero). Find the specific work (kJ/kg) and the power (kW) produced.

one kg of air is compressed in a cylinder according to the law PV^1.3= constant. If intital temperature is 100°C amd compression ratio is 15, find the work done and change in entropy of air.

A steam turbine has an inlet of 3 kg/s water at 1200 kPa and 350°C with a velocity of 15 m/s. The exit is at 100 kPa, 150°C and very low velocity. Find the specific work and the power produced.

A steam turbine receives 5,000 kg/hr of steam at 5 Mpa and 4000C and velocity of 25 m/sec. It leaves the turbine at 0.006 Mpa and 85% quality and velocity of 20 m/sec. Radiation loss is 10,000 kJ/hr. Find the Kw developed.

6. Superheated steam at 10MPA, 400°C is flow through an adiabatic nozzle of back pressure IMpa, and exit area of 10cm2. Find the Mass flow rate through the nozzle, the throat area that giveMaximum mass flow rat

o At the inlet to a certain nozzle, the enthalpy of the gas is 3000 kJ/kg and velocity is negligible. At the discharge end of the nozzle, the enthalpy is 2762 kJ/kg. The nozzle is horizontal and flow through the nozzle is adiabatic find the velocity of gas at the nozzle exit.
