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-m×2-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?

30°C, 10m/s 2m Electronic components inside D= 20cm Figure 5 You are designing components of an electronic systems that needs to be inside a 2 m long horizontal duct. The components are sensitive so the cooling mechanism is only done by air flowing over the duct at 30°C and 10 m/s. Initially you proposed a square cross-section with 20-cm length for the duct but is rejected by your client because they said a circular cross- section is better. If the surface temperature of the duct cannot exceed 60°C, find the maximum power rating in kW of the electronics devices that can be located inside the circular cross-section duct. Is it true that circular cross-section is better than a square one for this application?
