Frictional Pressure Drop in Pipes Calculator
HTML/JavaScript
This tool allows for interactive calculation of frictional pressure drop in pipes for single phase incompressible newtonian fluids. Calculates the Reynolds number and pressure drop based on the Darcy-Wisebach equation with the Haaland friction factor correlation. Results are displayed dynamically and can be exported as pdf.
Chemical Plant Capital Cost Estimator
HTML/JavaScript
This program allows easy calculation of the total fixed capital cost of a chemical plant using the detailed factorial method outlined by Towler & Sinnott. Select from a list of over 50 equipment options, or specify custom equipment in a range of materials. Adjustment for inflation (CEPCI) and currency conversion is provided. Final ISBL and Total Fixed Capital Cost of the plant is calculated. Export a full report of the results directly within the browser.
Heat Exchanger Design Calculator
HTML/JavaScript
Calculates critical parameters required for design of a shell-and-tube heat exchanger from typical thermodynamic and design inputs in SI units. Key results determined are: Required heat exchange area (A), required cold stream flowrate, number of tubes, as well as useful supporting data such as Reynold’s number and tube-side pressure drop. Features dynamic visualisation as well as comprehensive error detection. Can be used to quickly mock-up a heat exchanger design.
Fixed Bed Pressure Drop Calculator
HTML/JavaScript
A responsive application which determines the pressure drop (SI) across a packed bed using the Ergun equation. Additionally Reynold’s number is determined to indicate the flow regime.
