Consider a 0.6-cm (inside diameter) circular tube that is of sufficient length that the flow is hydrodynamically fully developed. At some point beyond the fully developed location, a 1.2-m length of the tube is wound by an electric resistance heating element to heat the fluid, an organic fuel, from its entrance temperature of 10 °C to a final value of 65 °C. Let the mass flow rate of the fuel be 1.26×10-3 kg/s. The following average properties may be treated as constant: Pr= 10 p=753 kg/m3 c=2.092 kJ/kg.K k=0.137 W/m.K μ=0.00065 Pa.s Calculate and plot both tube surface temperature and fluid mean temperature as functions of tube length. What is the highest temperature experienced by the fluid?
