6.A pressurized cylindrical tank, 5.0 m in diameter, contains water which emerges from the pipe at point with a velocity of 84 m/s. Point A ls 10m above point B
and point C is 3m above point B. The area of the pipe at point is o.08m^2 and the
pipe narrows to an area of 0.07m at point C Assume the water is an ideal fluid
in laminar flow. The density of water is 1000kg/m". What is the rate which the
water level in the tank is lowering?
