Pypley
iPhone / Utilitaires
Pypley calculates flow rate, pressure drop, and pump performance for circular pipe systems with Newtonian liquids. Build serial pipe systems using a pump database, fittings, and valves, with support for custom pumps and fittings stored via iCloud. Designed for hydraulic and process engineers, Pypley supports early-stage design and quick estimations.
Key Features:
* Converts all project parameters between Metric and US Imperial units.
* Calculates flow rate, pipe velocity, and pressure drop in pipes.
* Generates pressure loss tables for fittings and pipes in the system.
* Includes native and customizable pump database.
* Adjusts pump performance via speed (RPM) and impeller diameter.
* Plots pump and system performance curves.
* Computes K values for fittings using 3K and 2K methods.
* Determines Reynolds number for each pipe diameter.
* Calculates pipe friction factor using the Colebrook equation.
* Reports pump discharge pressure and pressure at each pipe’s start.
* Evaluates NPSHr and NPSHa to assess pump cavitation risk.
* Supports custom fitting lists with Kv/Cv coefficients or pressure/flow data.
* Detects negative pressure in pipelines.
* Identifies when centrifugal pumps reach maximum flow capacity.
* Organises projects chronologically, with newest first.
* Provides an expanded pipe material library with enhanced data.
Pypley is a design tool for hydraulic and process applications, ideal for initial designs or rapid calculations. Note: Pypley does not support parallel or network flow analysis.
Disclaimer: While we strive for accuracy and will address any issues, the developer is not liable for errors or omissions in Pypley’s calculations.
