Consider pressurized liquid water flowing at m . 0.1 kg/s in a circular tube of diameter d 0.1 m and length l 6 m. (a) if the water enters at tm, i 500 k and the surface temperature of the tube is ts 510 k, determine the water outlet temperature tm, o. (b) if the water enters at tm, i 300 k and the surface temperature of the tube is ts 310 k, determine the water outlet temperature tm, o. (c) if the water enters at tm, i 300 k and the surface temperature of the tube is ts 647 k, discuss whether the flow is laminar or turbulent.
