stationary diesel engine

Hot exhaust gases leaving a stationary diesel engine at
450C enter a l5-cm-diameter pipe at an average velocity ofa3.6 m/s. The surface temperature of the pipe is 180C. Determine
the pipe length if the exhaust gases are to leave the pipe
at 250C after transferring heat to water in a heat recovery unit.
Use properties of air for exhaust gases.
Water at 54°F is heated by passing it through 0.75-in.-internal-diameter thin-walled copper tubes. Heat is supplied tothe water by steam that condenses outside the copper tubes at250°F. If water is to be heated to 140°F at a rate of 0.7 lbm/s,determine (a) the length of the copper tube that needs to beused and (b) the pumping power required to overcome pressurelosses. Assume the entire copper tube to be at the steam temperatureof 250°F.
