A spherical tank has a circular orifice in its bottom throughwhich the liquid flows out. The flow rate through the holecan be estimated by : Q=C*A*sqrt(2*g*h)
C=orifice coefficient=.55
A=orifice surface area
g=gravitational constant=9.81
h=height of water
How long will it take for the water to flow out of the 3 mdiameter tank with an initial height of 2.75 m. Note that theorifice has a diameter of 3cm
