Water flows with mass flow rate of 0.1K(g)/(s) in a thin walled stainless steel pipe heated uniformly with inner diameter of
12.7 mm and length of 10 m . The inlet and outlet temperatures of the water are 25\deg C and 75\deg C, respectively. Determine
(a) the required heat and (b) surface temperature at the pipe exit?
\rho =1000k(g)/(m^(3)),Cp=4000(J)/(k)g*K,Pr=10,k=0.48(W)/(m)*K,\mu =2\times 10-3Pa.s
