Engineering Calculators
A curated suite of specialized online engineering calculators for mechanical, civil, and chemical engineers working with fluid systems. Perform essential calculations for pump sizing, pipeline design, system analysis, and more. These tools address key challenges in hydraulic engineering and fluid dynamics, including flow rate, velocity, pressure drop, and head conversions.
Flow Rate to Velocity Calculator
Instantly calculate flow rate, velocity, or pipe diameter for incompressible fluids. This essential tool for system design is based on the fundamental continuity equation, critical for HVAC and piping.
Total Time & Flow Rate to Total Volume Calculator
This calculator will calculate the volume of substance flowed over a set period of time at a specified volumetric flow rate.
Pipe Pressure Drop Calculator
Calculate frictional pressure loss in straight pipes for single-phase Newtonian fluids. Uses the Darcy-Weisbach equation and Colebrook-White approximation. Essential for pump sizing and system design.
Fluids Density Calculator
Calculate the density of a wide range of petrochemicals, refrigerants, and common fluids using temperature and pressure. Supports more accurate results in pressure drop and flow rate calculations elsewhere in this suite.
