Problem 07.150 - Kitchen Water Flowing Over a Pipe Kitchen water at 10°C flows over a 10-cm-diameter pipe with a velocity of 2.1 m/s. Geothermal water enters the pipe at 90°C at a rate of 1.25 kg/s. For calculation purposes, the surface temperature of the pipe may be assumed to be 70°C. If the geothermal water is to leave the pipe at 50°C, determine the required length of the pipe in meter (m). (For both water streams, use k = 0,631 W/m-K, Pr = 4.32, v=0.658x10-6 m2/s, and cp-4179 J/kg-K). The required length of the pipe is [ m.
