Yes. Pipe Flow Advisor can calculate the approximate flow rate of water in part full channels (due to flow under gravity conditions).

It can also calculate the time required for a tank to empty (with flow under gravity) for a specific height of water in a particular shape of tank.

Pipe Flow Advisor cannot calculate flow rates or emptying times for fluids other than water since it use the Manning Formula to estimate the flow rate results and this equation only gives estimates for fluids similar to water.

The software can also perform calculations to determine the volume of fluid within a specific shape of container. It can calculate volume of fluid and weight of fluid for liquids other than water in these case, where the density data is specified.
