## Pypley Description
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.

## Pypley Reviews in United Kingdom

### ****- "Very useful"
As a mechanical engineer I constantly need to verify hydraulic pipe sizing and pump capacity. So I was always looking for something that can easily cross check my work like a second eye and this application is amazing in this regard. I just wish if the pumps selection are actual pumps from the market so you can just pick your selection and quickly check things in and that’s why I went for 4 starts instead of 5 :) .

### ****- "Very detailed application"
I have been looking for an application that can calculate flow rate of fluids with different densities and viscosities and this one does it.
-- RFisher1, 2021-08-12

### ***** "Great App"
Definitely worth spending some time in the tutorials. App very easy to use and accurate results. I would definitely recommend.
-- Matheus DS, 2020-11-19

### ***** "Great App"
Recently downloaded this app to help with general pipework calculations. Can’t fault it 5⭐️
