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 transfer from water to ambient air.
(2) Find the actual external surface temperature.

Dr. Clark designed a system capable of cooling the air of a house using water in river. The main component is stainless steel pipe (k=15.1 W/mK, Di=0.15m Do=0.152m) submerged in a river with a water temperature T_fluid=17 C. The warm air from the house enters this cooling pipe at a volume flow rate 0.025 m3/s, and T_m,i=27 C. The exit temperature is expected to be T_m,o=20 C. The convection heat transfer coefficient between the pipe external surface and water is...
