When we determine the relative magnitude of forced convection and free convection, we use the ratio of GrL/ReL2. Why not use GrL/ReL ? (5) \# have relation as R2GrL, and it use for the Predic
2. In heat exchanger design, the maximum heat transfer rate is expressed by Cmin×ΔTmax. Why is Cmin instead of Cmax used in the calculation? (5)
