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.
