We want to generate steam at 300 C 20 bar at 1000 kg/min from water at 60 C, 20 bar. To do this we will use oil at 500 C which will leave the steam generator at 350 C. (Cp = 0.9 cal/g-C) What is the rate of oil required?

9. Helium is compressed in an adiabatic cylinder from 70°F, 10 ft³, 15 psia to 1 ft³ according to the relation pVK = c. Find the work nonflow, the final temperature and the change of enthalpy.

A steady stream of steam passes through an adiabatic turbine. It enters at 10 MPa, 450 °C and 80 m/s and at the exit it is 500 KPa, 40% quality and 30 m/s. The mass flow of the steam is 12 kg/s. a) With the power that comes out of the system, 252 100 W bulbs can be lit. Calculate the efficiency of the system. b) What is the area of ​​the duct at the entrance? c) What is the volumetric flow at the outlet? d) What is the temperature of the steam at the outlet?

A- An adiabatic steam turbine has an inlet of 2 kg/s water at 100 bar, 400 °C with velocity of 15 m/s. The exit is dry saturated at 100 kPa and very low velocity. Find the power produced.
