Water flows through a pipe of varying cross-section and varying elevation at the rate of 22.2m3/min. At one section of the pipe 3 m from the ground, the radius of the pipe is 36 cm and the pressure is 12 N/cm^2.What is the pressure at a section where the radius of the pipe is 18cm and is 0.7 m from the ground level?
