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...
