Combustion gases passing through a 0.08-m-internal-diameter circular tube are used to vaporize waste water at atmospheric pressure. Hot gases enter the tube at 115 kPa and 250°C at a mean velocity of 5 m/s and leave at 150°C. The average heat transfer coefficient is 120 W/m2·K and the inner surface temperature of the tube is 110°C. The properties of air at the average temperature of (250+150)/2=200°C are: cp = 1023 J/kg.°C R = 0.287 kJ/kg.K A) Determine the mass flow...
