A liquid with specific gravity of 1:26 is being pumped from A to B through the pipeline. At A, the pipe diameter is 24 in and the pressure is 45 psi. At B, the pipe diameter is 12 in and the pressure is 50 psi. Point B is 3 f t lower than A. Find the flow rate if the pump puts 22 hp (16 kW) in to the flow. Neglect head losses.
