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.

ASME B31.3 Provides formula and guidelines for calculation of pipe under pressure. Though the formula is quite simple, finding correct values of individual factors can be tricky sometimes. This process pipe thickness calculator uses following formula for calculation of wall thickness. 304.1.2 (a) equation 3a : Seamless Pipes : Design Thickness t = (PD)/2(SE+PY) Welded Pipes : Design Thickness t = (PD)/2(SEW+PY) For complete explanation, visit : http://www.pipingengineer.org/pipe-thickness-calculator/
