- Correlation of experimental data for the average heat transfer coefficient for turbulent flow through tubes is given by NUD =hD/k=0.023 (Rep) 0.8 (Pr) 1/3 The Reynolds number, Re₁ = πD/v, is based on the tube diameter D, the average flow velocity ū and the kinematic viscosity v. Consider the flow of air and of water through tubes of identical size. Assume that the average velocity is the same for both fluids. If the average temperature for both fluids is 80°C, determine the ratio of the heat transfer coefficient of water to that of air.arrow_forwardDon't use ai to answer I will report you answerarrow_forwardDon't use ai to answer I will report you answerarrow_forward
