Consider a two phase flow of air-water in a vertical upward stainless steel pipe with an inside diameter of 0.0254 m. The two phase mixture enters the pipe at 25°C at a system pressure of 201 kPa. The superficial velocities of the water and air are 0.3 m/s and 23 m/s, respectively. The differential pressure transducer connected across the pressure taps set 1 m apart records a pressure drop of 2700 Pa and the measured value of void fraction is 0.86. Using the concept of Reynolds analogy determine the two phase convective heat transfer coefficient.
