Pypley

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.
