A thin flat plate 15 cm square is suspended from a balance into a uniformly flowing stream
Question:
A thin flat plate 15 cm square is suspended from a balance into a uniformly flowing stream of engine oil in such a way that the oil flows parallel to and along both surfaces of the plate. The total drag on the plate is measured and found to be 55.5 N. If the oil flows at the rate of 15 m/s and at a temperature of 45?C, calculate the heat-transfer coefficient using the Reynolds analogy.GIVENEngine oil flowing along a thin flat platePlate dimensions = 15 cm × 15 cm = 0.15 m × 0.15 mEngine oil velocity (U??) = 15 m/sEngine oil temperature (T??) = 45?CTotal drag force (D) 55.5 NASSUMPTIONSSteady stateConstant fluid propertiesRadiative heat transfer isnegligible
