Air enters a 18cm diameter underwater duct at 50 °C at a volumetric flow rate of 0.180 m³/s. The air is cooled by the water outside and leaves at 15.5 °C. If the average heat transfer coefficient inside the pipe is 65 W/m²K and the tube temperature is constant at 10 °C, determine the steady rate of heat transfer to the air. Assume the density of air to be 1.281kg/m3 and its specific heat capacity is 1006J/kgK. ONW Oww.
