Problem \# 1−50 points To determine the heat transfer characteristics of a small diameter 20 mabe at 25∘ C. The stainless-steel tube, a test is set up to heat a certain fluid that ented as thin walled. A constant tube wall temperature of 125∘ C is maintained by an electric res thisth a fully developed around the outer surface of the tube. If fluid centers the tube with a fally developed estimate the length at which the fluid velocity profile and a uniform temperat properties are: Density=850 kg/m3;cₚ=3500 J/kg.K,μ=2×10³ kg/s.m,k=0.5 W/m.K, and Pr=10 Assume fully developed flow. Use the suggested Nusselt number correlations for the laminar and the tarbulent flows.
