Assume the heat transfer in Problem 3.213 came from a 200?C reservoir. What is the total entropy generation in the process?
Problem 3.213
Water in tank A is at 250 kPa with quality 10% and mass 0.5 kg. It is connected to a piston/cylinder holding constant pressure of 200 kPa initially with 0.5 kg water at 400?C. The valve is opened, and enough heat transfer takes place to have a final uniform temperature of 150?C. Find the final P and V, the process work, and the process heat transfer.
These concentrations were measured when the trailers were 2 years old and the emission rate had significantly decreased by that time. New material rates as high as 290 mg/hr have been reported. Calculate the steady state HCHO concentration (ug/m3) re..
