Transcribed image text: In a gas-fired boiler, water is being boiled at 120 degree C by hot air flowing through a 5-m-long, 5-cm-diameter tube submerged in water. Hot air enters the tube at 1 atm and 300 degree C at a mean velocity of 7 m/s. and leaves at 150 degree C. If the surface temperature of the tube is 120 degree C, determine the average convection heat transfer coefficient of the air Learn More
