Steam flows steadily through a turbine at a rate of 45,000 lbm/h. It enters at 1000 psi and 900°F and leaves at 5 psi as saturated vapor. If the power generated by the turbine is 4 MW, determine the rate of heat loss from the steam.
Air (MW=29 g/mol) at 115.00 kPa and 285.00 is compressed steadily to 600.0 kPa. The mass flow rate of the air is 2.00 kg/s and a heat loss of 32.1 kW occurs during the process. You may assume that changes in kinetic and potential energy are negligible, the temperature of the surroundings is 25 ∘C, and that the CP of air is 3.5 R.

1. Steam at a pressure of 2MPA and temperature 300°C is passed at a constant rate into a desuperheater unit. The desuperheater is accomplished by continuously spraying water at 95 °C onto incoming superheated steam. The amount of water injected is so regulated that both the water and superheated steam finally change into dry steam at 2 MPa. If the resulting mixture of dry saturated steam leaves the desuperheater at 2MPA and the rate of I kg/s, find the mass of superheated steam used per hour and the mass of water to be injected per hour. Fond also the diameter of the pipe through which the superheated steam flows to the superheater if the speed of the steam through the pipe is not to exceed 25m/s..
R-134a enters a compressor as a saturated vapor at 80 kPa and exits at a pressure of 400 kPa. If 44 kJ/kg of work is required and 5 kJ/kg of heat is lost to the surroundings. What is the outlet temperature. Round your answer to the nearest whole number.
The case of a piston-cylinder device provided with stops is presented. Initially, the water supports the weight of the piston, and the force of the atmosphere is 300 kPa and 0.4 m3/kg. The water is heated until it reaches a saturated steam condition and the plunger rests on the stops. With the piston on the stops, the water is heated to a pressure of 700 kPa. Plot the curves of the processes on the p-V and T-V diagrams indicating the initial and final states of the guide. On both the p-V and T-V diagrams plot the isotherms passing through both states, and show their values in °C.
A man purchases a turbine for use in his factory. He sets it up so that there is steam entering at 5000 kpa and at 873.15 Kelvin at a constant rate of 100 m/sec. This steam seems to leave the turbine at 100 m/sec and of 95% quality at a pressure of 0.01MPa. The manufacturer sticker claims the turbine has a power output known to be 56400 Joules per second. Find the theoretical mass flowrate of the steam through the device [kg/sec] and the area of the outlet [m^2]
