A batch of 2-cm-thick stainless steel plates

A batch of 2-cm-thick stainless steel plates (k = 21 W/m·K, r = 8000 kg/m3 , and cp = 570 J/kg·K) are conveyed through a furnace to be heat treated. The plates enter the furnace at 18°C, and travel a distance of 3 m inside the furnace. The air temperature in the furnace is maintained at 950°C with a convection heat transfer coefficient of 150 W/m2 ·K. Using EES (or other) software, determine how the velocity of the plates affects the temperature of the plates at the end of the heat treatment. Let the velocity of the plates vary from 5 to 60 mm/s, and plot the temperature of the plates at the furnace exit as a function of the velocity
