For seaworthiness trial of a new ocean-going vessel design, the total convective heat transfer rate of a fully turbulent water flow over a 10-mx2-m side of a flat plate was measured to be 77.2 kW under a specific steady condition in a test setting. The conditions are: velocity of the water is 0.5 m/s along the 10-m side of the surface; water temperature is 18°C; and surface temperature was uniform at 22°C. What is the friction force (skin friction drag) due to the water flow on the surface?
