A liquid is entering a 10 m long pipe of 0.2 m diameter at 25°C with an average velocity of 0.02 m/s. The pipe is kept at a constant surface temperature of 40°C. Assume the flow is both hydrodynamically and thermally fully-developed in the pipe. Find out the outlet temperature. Justify if the assumption of fully-developed flow is appropriate. The properties of the fluid can be assumed constant with following values Density: 484.2 kg/m³; Specific heat capacity: 2802 J/kg-K; Thermal conductivity: 0.0904 W/m.K; Dynamic viscosity: 9.197 x 10-5 kg/m-s; Prandtl number: 2.85. 29.3℃
