Predict the boiling heat-transfer coefficient for water under pressure boiling at 250 F for a horizontal surface of 78-in.-thick stainless steel having a k of 9.4 btu/h . ft . F. The heating medium on the other side of this surface is a hot fluid at 290 F having an h of 275 btu/h.ft2.F. Use the simplified equations. Be sure and correct this h value for the effect of pressure.
