Water flows steadily through a section of piping in a heat exchanger at a constant pressure of 1.5 bar, entering as a vapor and exiting as a liquid. One side of the pipe is maintained at 400K and receives 20 kJ/s of energy by heat transfer, while the other side of the pipe is maintained at 800K and rejects 40 kJ/s of energy by heat transfer. Is this process possible, impossible, or indeterminate from the information given

Apreheater involves the use of condensing steam at 100°c on the inside of a bank of tubes to heat air that enters at 1 atm and 25°c. the air moves at 5 m/s in cross flow over the tubes. each tube is 1 m long and has an outside diameter of 10 mm. what is the minimum value of nl needed to achieve an outlet temperature of t 75 c? what is the corresponding pressure drop across the tube bank?
