14. A bubbly mixture of gas and liquid flows up a vertical glass tube with an internal diameter of 25 mm. The liquid flow is controlled to be 0.02 litres per second, and the gas flow is 10 litres per second. The bubble velocity is determined photographically to have a velocity of 30 ms -¹. Determine the gas void fraction for the two-phase mixture and the liquid velocity. Answer: 0.68, 0.13 ms-1
