Question:
For a study on global warming, an electronic instrument has to be designed to map and the CO2 absorption characteristics of the Pacific Ocean. The instrument package resembles a flat plate with a total (upper and lower) surface area of 2 m2. For safe operation, its surface temperature must not exceed the ocean temperature by 2?C. To monitor the temperature of the instrument package, which is towed by a ship moving at 20 m/s, the tension in the towing cable is measured. If the tension is 400 N, calculate the maximum permissible heat generation rate from the instrument package.GIVENA flat plate towed through waterTotal surface area (A) = 2 m2Speed through the water (U??) = 20 m/sTowing cable tension (T) = 400 NMaximum plate surface temperature ?? ocean temperature (??Tmax) = 2?CASSUMPTIONSSteady stateEdge effects are negligibleEffects due to the towing cable are negligibleThe speed given is speed relative to the waterThe water temperature is about 20?CThe length of the plate in the direction of motion is notknown
