Volume of Digested Sludge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sludge Volume = (Weight of sludge)/(Water Density*Specific Gravity of Sludge*Percent Solids)
V_s = (W_s)/(ρ_water*G_s*%s)
This formula uses 5 Variables

Variables Used

Sludge Volume - (Measured in Cubic Meter) - Sludge Volume is calculated by dividing the settleability by the MLSS concentration.
Weight of sludge - (Measured in Kilogram) - Weight of sludge is the force acting on the sludge due to gravity.
Water Density - (Measured in Kilogram per Cubic Meter) - Water Density is mass per unit of water.
Specific Gravity of Sludge - Specific Gravity of Sludge is the ratio of the density of sludge to the density of standard compound.
Percent Solids - Percent Solids refer to the ratio of the solid mass of a material present in a liquid (or semi-liquid) sample.

STEP 1: Convert Input(s) to Base Unit

Weight of sludge: 20 Kilogram --> 20 Kilogram No Conversion Required
Water Density: 1000 Kilogram per Cubic Meter --> 1000 Kilogram per Cubic Meter No Conversion Required
Specific Gravity of Sludge: 2 --> No Conversion Required
Percent Solids: 0.7 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_s = (W_s)/(ρ_water*G_s*%s) --> (20)/(1000*2*0.7)

Evaluating ... ...

V_s = 0.0142857142857143

STEP 3: Convert Result to Output's Unit

0.0142857142857143 Cubic Meter --> No Conversion Required

FINAL ANSWER

0.0142857142857143 ≈ 0.014286 Cubic Meter <-- Sludge Volume
