# Quantity of Seepage Calculation

Posted by Dinesh onUse the simple hydraulics and waterworks calculator to calculate **Quantity of Seepage**. The quantity of seepage can be computed directly from a flow net. Or, in certain instances, from charts or equations without the construction of a flow net. The formula for computing the quantity of seepage from a flow net is `Q = k * (n`

._{f} / n_{d}) * h_{t} * L

### Formula:

Q = k × (n_{f} / n_{d}) × h_{t} × L

- k - effective coefficient of permeability which is ? k
_{max}k_{min} - n
_{f}- number of flow channels of net - n
_{d}- number of equipotential drops of net - h
_{t}- head difference between headwater and tail water - L - length of dam to which the flow net applies
- Q - quantity of seepage in length of dam under consideration
