Question

Flow from a tank with falling head. For the tank shown in figure below, find the time required
to drain the tank from a level of 3.0 m to 0.5 m. The tank has a diameter of 1.5 m, and the
nozzle has a diameter of 50 m.
dh
- D,-
Assumption: Equation developed by assuming that diameter
of fluid flowing from the nozzle is the same as the diameter of
the nozzle itself. This is very nearly true assumption for a well-
rounded nozzle as shown in this figure
DB

Figure below was used to derive the equation used to determine the time it takes to empty
the tank from hi to h2. The equation was derived by considering that the tank is open and
hence at 0 gage pressure above the water. If the tank is sealed and pressure of 5.0 psig is
above the water in the tank, compute the time required to empty the tank if the original depth
is 15 ft. The tank diameter is 12 ft and the orifice diameter is 6 in.
dh
Note: If the tank is sealed with a pressure, p, above the fluid,
the piezometric head p/y should be added to the actual liquid
depth before completing the calculations called for in the
equation.
