The General Pluming Calculator formulas include the following: Rolling Offset Lengths
The Flow Equations equations include:
The Volume and Weight equations include the volume and content weight of:
The Other equations include:
The mean density (mD) can help the user calculate the content weight of containers (pipes and tanks) that hold substances other than water (e.g. diesel fuel or sludge). The calculations require the user to enter the dimensions of the object (e.g. pipe, tank) to compute the volume. For the weight equations, use the dimensions and the mean density of the substance in the object. Note: The mean density of water is 1,000 kg / m3. Use this in the mass/weight equations to approximate the weight of water in the tank or pipe.
