CIP Velocity

Calculate the liquid flow required to achieve a declared average cleaning-in-place velocity in a full circular pipe.

OPERATING LIMITS — Hydraulic cleaning calculation only; validate chemistry, temperature, time, Reynolds number and circuit conditions.

INPUT DESIGN PARAMETERS (SI)

Pipe Diameter[mm]

Target Velocity[m/s]

m/s

CALCULATED SPECIFICATION OUTPUT

Required Flow (L/hr)

10603 L/hr

Required Flow (GPM)

46.7 GPM

Technical Methodology & Engineering Principles

GOVERNING EQUATION

Pipe area A = πD²/4; required flow Q = A × target velocity, converted to L/h and US gal/min.

Assumptions & Scope

Full circular pipe and average bulk velocity. Pump head, fittings, spray devices, return restrictions, fluid properties, and cleaning validation are outside this calculation.

Operating Range & Boundary

Pipe diameter and target velocity must be positive.

Peer Reference: Continuity equation for incompressible flow; verify the hygienic-cleaning velocity against the equipment owner and validated cleaning procedure.
