Repeat Problem 6.9 using a surface temperature of 400°C for the mechanically polished stainless steel surface.

Problem 6.9

Water at atmospheric pressure is boiling on a mechanically polished stainless-steel surface that is heated electrically from below. Determine the heat flux from the surface to the water when the surface temperature is 106°C, and compare it with the critical heat flux for nucleate boiling. Repeat for the case of water boiling on a Teflon-coated stainless-steel surface.
