### Drain Pipe Slope Calculator (According to International drainage pipe flow calculator in senegal

Drain Pipe Anatomy. The following diagram lays out the different terms that are used in the calculator How to Use the Calculator. First, figure out the diameter of the pipe you are working with. For household sinks, the drain pipe diameter is often either 1.5 or 2. Toilet waste lines are often 3 or 4. How do you calculate the velocity of a pipe?How do you calculate the velocity of a pipe?Once you know the velocity of the gravity flow, you can also find the discharge, Q, by multiplying the cross-sectional area of the pipe by the flow speed Q = A * v. Make sure to use our flow rate calculator to convert between the discharge (volumetric flow rate) and the mass flow rate.Pipe Flow Calculator HazenWilliams Equation
