General Plumbing Calculators

• Rolling Offsets (Run)  – The Rolling Offset (Run) function computes the run length a rolling offset based on the offsets and fittings. (see diagram).
• Rolling Offsets (Travel)  – The Rolling Offset (Travel) function computes the travel pipe length a rolling offset based on the offsets and fittings. (see diagram).
• Pipe Grading - The amount of drop needed over a run to maintain a specified grade
• Diagonal of a Square - This is a simple calculation to assist in computing the diagonal of a square.
• Diagonal of a Box - This computes the length of the diagonal of a box (T) based on sides of length R, S and U.
• Flow Rate - This computes flow rate based on the total volume and the time it took to accumulate.
• Pipe Flow Volume  - This computes the total volume from a pipe based on the flow rated and the duration of flow.
• Volume of a Pipe
• Weight of Pipe Contents: Default is water.  Also see Weight of sea water in pipe
• Volume of a Cylindrical Container (e.g. hot water tanks),
• Weight of Water in a Cylindrical Tank (e.g. hot water tanks),
• Volume of a Spherical Container,
• Weight of Water in a Spherical Container
• Volume of a Rectangular container
• Weight of Water in a Rectangular Container, and a 
• Capillary Rise - The height of water in a small tube due to capillary force.
• Snow Water Equivalence - The volume of water created by an area and depth of snow.
• Pore Water Pressure - Pressure of uplift from the water table.
• Pressure Head - The Potential Gravity-Fed Water Pressure from a Tank (a.k.a. Pressure Head) equation calculates the water pressure that can be realized below a tank based on the height of storage.
