Flow Rate to Pressure Calculator
Calculate pressure drop from flow rate in pipes and ducts. Convert between flow rate and pressure for hydraulic systems, plumbing, and HVAC applications.
Step 1: Flow Parameters
Understanding Flow Rate & Pressure
Pressure drop in a pipe system depends on flow rate, pipe diameter, fluid properties, and pipe roughness. Higher flow rates and smaller diameters result in greater pressure losses.
Step 2: System Details
Pressure Drop Calculation
Pressure drop is calculated using the Darcy-Weisbach equation, considering pipe roughness, fluid viscosity, and flow characteristics (laminar or turbulent).

Detailed Pressure Drop Analysis
Pressure Drop Formula
ΔP = f × (L/D) × (ρ × V²/2)
The Darcy-Weisbach equation calculates pressure drop (ΔP) where f is friction factor, L is pipe length, D is diameter, ρ is fluid density, and V is flow velocity. Friction factor depends on Reynolds number and pipe roughness.
