A10-m long and 10-mm inner-diameter pipe made of commercial steel is used to heat a liquid in an industrial process. the liquid enters the pipe with ti = 25‘c, v: 0.8 m/s. a uniform heat flux is maintained by an electric resistance heaterwrapped around the outer surface of the pipe, so that the fluid exits at 75": assuming fully developed flow and taking theaverage fluid properties to be p = 1000 kg/m3. cp = 4000 j/kg- k, u = 2 x 10—3 kg/m - s. k = 0.48 w/m - k, and pr = 10,determine: (a) the required surface heat flux @" produced by the heater(bl the surface temperature at the exit, 7's(6) the pressure loss through the pipe and the minimum power required to overcome the resistance to flow.
