Unformatted text preview: diameter inlet pipe as shown in Figure. The turbine discharge pipe has a 4-ft inside diameter. The static pressure at section (2), 10-ft below the turbine inlet, is 10-in Hg vacuum. If the turbine develops 2500 hp, determine the power lost from (1) to (2) . 7. A conical tube is fixed vertically with its smaller end upwards. The velocity of flow down the tube is 4.5-m/s at the upper end and 1.5-m/s at the lower end. The tube is 1.5-m long and the pressure head at the upper end is 3.1-m of the liquid. The loss in the tube expressed as a ‘head’ is -g 2 ) V V ( 3 . 2 2 1 where V 1 and V 2 are the velocities at the upper and lower ends respectively. What is the pressure at the lower end ? 2/2...
