Question: Condensing steam at 150oC is used on the inside of a bank of tubes to heat a cross-flow stream of CO2 that enters at 3

Condensing steam at 150oC is used on the inside of a bank of tubes to heat a cross-flow stream of CO2 that enters at 3 atm, 35oC, and 5 m/s. The tube bank consists of 100 tubes of 1.25-cm OD in a square in-line array with Sn = Sp =1.875 cm. The tubes are 60 cm long. Assuming the outside-tube-wall temperature is constant at 150oC, calculate the overall heat transfer to the CO2 and its exit temperature.
