Water (density p=1000 kg/m^3) is discharging from through a hole at the bottom of a graduated cylinder. the mass flow rate exiting the container may be approximated by: mass flow rate = c*p*a*(2*g*y)^(1/2)where c is the dimensionless discharge coefficient , a is the area of the discharge hole, g is the acceleration due to gravity, and y is the water height in the container. the diameter of the graduated cylinder is 8 cm. for the following givens, estimate the time to empty half the water from the container. c= .6 a=.04 cm^2 g= 9.8 m/s^2 y(initial)= 20cm
