Air at 30°C flows over a flat plate 1.5 m long and 1 m wide. The plate surface is maintained at 70°C. If the desired rate of heat dissipation from the plate is 3 kW, determine the flow velocity of the air. -0.5 Remind that the average friction coefficient in laminar condition is Cf = 1.328 Rezº and the average heat transfer coefficient for a laminar-to-turbulent condition over the plate can be evaluated with Nuz = (0.037Rez0.8 - 871) Pr¹/3 Air properties: k = 0.02799 W/mK, p = 1.095 kg/m³, μ = 1.95 × 10-5 Pr = 0.703 Pas, Cp = 1007.2 J/kg K, Air at 30°C flows over a flat plate 1.5 m long and 1 m wide.
