## Calculators

Pump & Flow has a wide range of proven design tools for piping and pipeline systems. We use a mix of commercially-available software and code developed in-house based on our testwork. Some of these we make available free of charge, and invite users to put them to use to develop safe and efficient piping systems.

From slurry pump calculations to deposition velocity and much more, we are confident that you'll find what you are looking for in our calculators.

If you would like further assistance or support with your design, please reach out. We would be pleased to learn more about your project.

Filter calculators by:

### Slurry pump calculator

Comprehensive slurry pipeline tool with calculations for head loss, pump power, NPSH check, efficiency ratios and much more. Includes a function to generate a PDF report.

### Slurry Pump Head / Efficiency Ratios

Obtain head and efficiency ratios for your pump's duty point based on the properties of the slurry. Calculate the reduction in efficiency and head pressure for a given slurry.

### Non-Newtonian Head Loss

Calculate the head pressure loss or head pressure gradient generated by the flow of a non Newtonian slurry (slurries with high concentration of very fine particles can be considered non Newtonian)

### Concentration Conversion Calculator

Convert between mass flow rate (Cw), volumetric flow rate (Cv), and specific gravity (SG). Calculate the dry solids flow rate and other flow concentration properties for your slurry.

### Wall Thickness Calculator

Calculate piping wall thickness based on code ASME B31.3, AS 4041, and Polyethylene pipes. Obtain the required SCH (schedule) numbers for any pipe based on pressure and many other parameters.

### Durand, Cave & Wilson 2LM Calculator

Obtain the limit deposition velocity (or limit settling velocity) for your slurry using one of these three industry leading slurry correlation models. Calculate the minimum recommended flow velocity, LSV, LDV, etc.

### Tank Overflow Calculator

Use this calculator to properly size your tank overflow piping. Calculate piping size and liquid level based on two different criteria to ensure the correct functioning of your system.

### Newtonian Head Loss

Calculate head loss, Reynolds number, friction factor and many other parameters using our calculator for newtonian fluids. Calculate pressure loss for your pipeline and more.

### Moody Diagram

Use this Moody diagram calculator to get the Reynolds number for your input parameters, with an interactive real time graph. Laminar and turbulent flow calculator.

### 4 Component Model Calculator

Industry leading slurry head loss calculator based on the latest revision of Wilson's advanced Four Component Model (4CM). Get accurate results for pipeline design and calculations.

### DHLLDV Framework

Get the limit settling velocity (deposition velocity) for a given slurry using the DHLLDV Framework. This calculator provides a result that is in good agreement with the most accurate parts of many existing models.

### VSCALC Settling velocity

Get the settling velocity (deposition velocity) for a given slurry using the VSCALC program provided in the book "Slurry Transport Using Centrifugal Pumps", which combines Wilson's and Thomas's findings into one script.
