## What is HydroCalc Basic?

Pipe Headloss Calculator provides engineers, designers, and students with powerful tools for pipeline hydraulic analysis — without the hassle of complex manual computations.

Whether you’re sizing new pipelines or analyzing existing systems, the app delivers rapid, accurate results.

Key Features

Automatic Unit Conversion – Seamlessly switch between US Customary and SI units for length, flow, and diameter.
Pipeline-Specific Inputs – Enter pipeline length, flow rate, internal diameter, and pipe material.
Powerful Inverse Calculator – Set a target head loss and calculate the required diameter, flow, or length.
Instantly view flow velocity, friction head loss, fitting losses, and full system curve data.

With a clean interface and fast performance, this app is designed to save time and improve accuracy in hydraulic calculations — from the classroom to the field.
