In a refinery, hot flue gasses at 1800°c are cooled by a fluid at 25°c with the gas and liquid side heat transfer coefficients being 50 and 500 w/m2-k, respectively. the wall that separates the gas and liquid side is composed of stainless steel and has a thickness 1cm. assuming no contact resistances, determine: a)- the rate of heat losses per unit area from the gas to the liquid. b)- will the wall melt on the gas side? the solidus temperature of the stainless steel is 1400°c data for stainless steel: k-25 w/m. k
