Liquid Flow from Containers - Emptying Time

Calculator for estimating volume flow and time required to drain a container or tank through an aperture. Based on discharge equation V = Cd A (2 g H)^0.5. The calculator divides the container into slices and makes iterative calculations for improved accuracy.

Calculator

Inputs

Bottom Area of Tank/Container (m²)
