An aluminum sheet, 0.4 m tall, 1 m long, and 0.002 m thick is to be cooled from an initial temperature of 150?C to 50?C by immersing it suddenly in water at 20?C. The sheet is suspended from two wires at the upper corners.(a) Determine the initial and the final rate of heat transfer from the plate.(b) Estimate the time required.GIVENA vertical aluminum sheet in waterPlate dimensions: height (H) = 0.4 m, length (L) = 1 m, thickness (s) = 0.002 mInitial plate temperature (Tsi) = 150?CWater temperature (T??) = 20?CFinal plate temperature (Tsf) = 50?CASSUMPTIONSConstant and uniform watertemperature
