01
Pipe & Pressure Drop
Flow, velocity, head loss, pressure drop, Reynolds number, minor losses and pipe screening checks.
Offline engineering calculator · One-time purchase · Bilingual
Fluid mechanics calculations, organized as projects.
Fluid Mechanics Calc is built for pipe flow, pumps, open channels, weirs, orifices, Venturi meters, seepage, and dimensionless-number checks. No login, no server, and all projects stay local on device.
Core
Not a formula list. A project-based hydraulic workspace.
Create an engineering project, then add only the calculation items you need. Inputs start blank, accept engineering number formats, calculate automatically, save automatically, and show scope guidance.
02
Pumps & Water Hammer
Pump power, efficiency, NPSH, cavitation margin and Joukowsky rapid-closure surge estimates.
03
Channels & Metering
Rectangular and trapezoidal channels, Manning flow, critical depth, weirs, orifices and Venturi meters.
Offline by design, practical for field and study use.
No account, no internet requirement, no ads and no subscription. Language, appearance and unit system can be changed inside the app.
