Water enters a thin wall tube with length l = 5 m and diameter d = 0.25 inch. the internal roughness of the tube surface is e = 15 micrometers. a uniform heat flux of 45.1 kw/m2 is applied to the surface of the tube. the flow rate of the water is 0.5 gal/min and the inlet temperature is t = 10°c. the tube exits to atmospheric pressure. a.) determine the mean temperature of the flow leaving the tube. b.) determine the pressure at the inlet to the tube. c.) determine the surface temperature of the tube at the exit. d.) how long can the tube be before you will see local boiling at the surface of the tube at the exit?
