Saturated vapor water at 100 kPa enters an isentropic compressor and exits at 2 MPa. Note that isentropic implies adiabatic and reversible. a) What is the temperature of the outlet in \deg C. Round to one decimal place. b) How much work, in kJ/kg, must be used for this process? Round your answer to one decimal place. Hint: Don't use temperature to perform the interpolation!

D and e please

11-A piston-cylinder assembly initially contains refrigerant-134a (R-134a) at a pressure of 0.8 MPa and a temperature of 60°C. In the system where the piston can move freely, the temperature of R-134a is reduced to 32°C.Which of the following diagrams correctly represents the process?

Waste from a copper plating facility is being discharged into a receiving stream. The waste stream contains 3.5 mg/L copper with a flow of 4.0 x106 L/day. The receiving stream has an upstream flow of 2.6x107 L/day and 0.50 mg/L of copper. Assume complete and instantaneous mixing at the point where the streams meet and that the system is at steady state. a) Draw the stream disgram b) What is the copper concentration in mg/L immediately downstream of the copper plating facility? c) How many kg per day are contributed to the receiving stream by the copper plating facility? d) What percentage of all of the copper mass in the downstream water is contributed by the upstream flow?
