QUESTION 5 A 12-m-long and 11-mm-inner-diameter pipe made of commercial steel is used to heat a liquid in an industrial process. The liquid enters the pipe with T; = 20°C, V=0.8 m/s. A uniform heat flux is maintained by an electric resistance heater wrapped around the outer surface of the pipe, so that the fluid exits at 60°C. Assuming fully developed flow and taking the average fluid properties to be p = 992.1 kg/m2, k = 0.631 W/m-°C, Cp =...

Expansion joints are used to allow for thermal expansion bridges. A steel bridge with a single expansion joint must operate between temperature extremes -50 F and 150 F, the gap in the joint is fully closed and the bridge is 100 m long. The linear expansion coefficient of steel is 12 x 10^-6 (Celcius). What is the gap at -50 F? Express your answer in centimeters.

A 10 m long stainless steel (AISI 347) pipe is delivering saturated liquid water at 140 °C. The inner and out diameter is 20cm and 22cm, respectively. Ambient air at 27 °C flows over this pipe as cross flow at 5 m/s. The convection heat transfer between internal surface and water is 200W/m^2*K. If you need the external surface temperature in finding property of air, you can assume the pipe external surface temperature is 127 °C. (1) Find the heat...
