Water flows through a pipe with an exit velocity of 11 m/s through a pipe 46 m long made from Coarse Concrete with a diameter 30 mm. The pipe is inclined upwards, with a difference in height between the pipe entry and exit of 7 m. The pipe is discharging into the ambient atmosphere. Take the visocity of water as 0.001 Pa.s. Calcaulate the pressure at the pipe entry to acheive the required exit velocity. Give your answer correct to 3 significant figures.
