A cylindrical water tank open to the atmosphere, 10 m tall and 6 m in diameter, is mounted with its base 25 m above ground level, and filled with water.
Calculate
a) the water pressure and force at the base of the tank?
b) the pressure in a water pipe at ground level?
c) the speed with which water will push out of a leak at a height of 8 m above the ground?(hint: force is equal to horizontal rate of change of momentum of water)​
