Water Quantity Calculation for Concrete. For the calculation of water quantity for concrete, first of all, we have to find the quantity of cement. Just assume that the required volume of cement for the mix is 100 kg and W/C is 0.4. Water Quantity = Water-Cement Ratio x Volume of Cement. Water Quantity = 0.4 x 100 kg = 40 liters / 100 kg cement
