In one process there is a throttle valve through which water vapor is passed in a superheated state, the valve operates in a steady state at P = 100 kPa and T = 250 ºC. The pressure of the fluid leaving the valve is 50 kPa. An engineer suggested replacing the valve with a turbine, this in order to get a turbine job. I. Determine the physical state of the fluid leaving the valve and the temperature. II.Determine the speed at which entropy is generated in the valve per kilogram of water that enters.III.Determine the maximum work that can be produced by a turbine per kilogram of water that enters if the current that enters the turbine is identical to the current entering the valve and the outlet pressure of the turbine is P = 50 kPa.

An engineer has designed a valve that will regulate water pressure on an automobile engine.  The valve was tested on 220 engines and the mean pressure was 5.8 lbs/square inch.  Assume the standard deviation is known to be 0.6.  If the valve was designed to produce a mean pressure of 5.7 lbs/square inch, is there sufficient evidence at the 0.02 level that the valve does not perform to the specifications?

A conduit carrying water vapor has one inlet and two exits. At the inlet, the velocity 25 m/s, the pressure is 4 bar and the temperature is 350 Celsius. The area at the inlet is 0.2 m^2 . At both the exits, the temperature and pressure are 300 Celsius and 3 bar respectively. The volumetric flow rate is identical at the two exits. Assuming steady-state conditions, calculate the volumetric flow rate at the exits.
