# Sludge Weight Flow Rate Calculator

Posted by Dinesh onUse the simple wastewater calculator to calculate the sludge weight flow rate for the dewatering facility.

## Weight Flow Rate of Sludge Feed Calculation

### Formula:

W_{s} = [ (V) × (?) × (s.g.) × (% solids) × (60 min/h) ] / 7.48 gal/ft^{3}

- V = volume flow rate of sludge feed
- s.g. = specific gravity of sludge
- % solids = percent solids expressed as a decimal
- ? = density of water, 62.4 lb/ft
^{3}(994.6 kg/m^{3}) - W
_{s}= weight flow rate of sludge feed
