Question

You can neglect radiation at the bottom of the plate; the bottom side of the plate has water flowing underneath it. Often, when dealing with liquids (rather than gases), one can neglect radiation because heat transfer due to convection is so much larger (liquids tend to have higher convection coefficient values than gases).

An opaque, horizontal plate has a thickness of L = 21 mm and thermal conductivity k = 25 W/m.K. Water flows adjacent to the
260°C with ha = 40 W/m².K. The
bottom of the plate and is at a temperature of Tw= 25°C. Air flows above the plate at Ta
top of the plate is diffuse and is irradiated with G= 1450 W/m², of which 535 W/m² is reflected. The steady-state top and bottom
plate temperatures are T, = 43°C and T₂ = 35.1°C, respectively.
