An oil pump provides a pressure of 2.69 atm when attached to a vertical 8.65 cm pipe. The pipe gradually reduces in diameter as the pipe increases height. The oil velocity at the pump is 8.25 m/s. At the top of the pipe, the required oil velocity is 15.0 m/s. Determine the height of the pipe if the density of oil is 809.0 kg/m3.
