A piston-cylinder device contains 2 kg saturated water vapor at 600 kPa. The water expands adiabatically until the final pressure is 100kPa. And 1,465 kJ work is produced. a. What is the final temperature of the water? b. What is the change in entropy of the water? c. Is this process realistic? Use a T-s diagram and the Clausius relation to explain.
A 1600-ft-long sag vertical curve (equal tangent) has a PVC at station 120+00 and elevation of 1500 ft. The initial grade is -3.5% and the final grade is +6.5%. Determine the elevation and stationing of the low point, PVI and PVT.
If the tanker truck discharges into the top of the tank with no vapor control, the emission of gasoline vapors is estimated to be 2.75k*m^-3 of gas delivered to the tank.
