Oil at 60°C flows at a velocity of 0.26 m/s over a 8 m-long and 4.5 m-wide flat plate maintained at a constant temperature of 20°C. determine the rate of heat transfer from the oil to the plate if the average oil properties are rho = 880 kg/m³, μ = 0.005 kg/m·s, k = 0.15w/m·k, and cₚ = 2.0 kj/kg·k. the rate of heat transfer from the oil to the plate for the given properties of oil is ________ w.
