Question:
A 0.6-cm-thick flat plate of stainless steel, 7.5 cm wide and 0.3 m long, is immersed horizontally at an initial temperature of 980?C in a large water bath at 100?C and at atmospheric pressure. Determine how long it will take this plate to cool to 540?C.GIVENA flat stainless steel plate is immersed horizontally in waterPlate thickness (s) = 0.6 cm = 0.006 mPlate width (w) = 7.5 cm = 0.075 mPlate length (L) = 0.3 mInitial plate temperature (Tpi) = 980?C = 1253 KPressure = 1 atmWater bath temperature (Tb) = 100?C (saturation) = 373 KASSUMPTIONSThe heat fluxes from the bottom and top of the plate are equalThe plate ispolished
