Convert a flow rate
Convert L/h, L/min and m³/h to compare line capacities.
Method and assumptions
1 m³/h = 1 000 L/h; 1 L/min = 60 L/h
Liquid volumetric flow only. Does not convert mass flow or normalised gas flow.
Results are rounded for display; assumptions and input accuracy limit actual precision.

Pipe velocity and volume
Estimate average liquid velocity and volume in a full pipe.
Method and assumptions
A = π(D/1 000)²/4; V = A × L × 1 000; v = Q/(3 600 000 × A)
Full circular pipe, actual internal diameter D in mm, length L in m and flow Q in L/h. DN is not the internal diameter. Excludes bends and fittings; does not calculate pressure losses, pump pressure or cleaning effectiveness.
Pipe velocity guidelines
Transfer of low-viscosity liquids: around 1 to 2 m/s on the discharge side is an initial order of magnitude. Product properties, viscosity, pressure losses, foaming and product sensitivity may require a different velocity.
CIP of full pipework: a range of 1.5 to 3 m/s is commonly considered for low-viscosity cleaning solutions to strengthen mechanical action. This guideline does not directly apply to spray balls, filters or heat exchangers.
Velocity alone guarantees neither turbulence nor cleanliness. Diameter, viscosity, actual circulation in each branch, chemistry, temperature and time must be assessed. Pump flow and pressure are sized for the circuit; the protocol is validated on the installation.

Cylindrical tank volume
Calculate the internal volume of a straight cylindrical body from its diameter and height.
Method and assumptions
V(L) = π(D/1 000)² × (H/1 000) × 1 000/4; 1 hL = 100 L; 1 m³ = 1 000 L
D and H are internal dimensions in mm of the cylindrical body only. Excludes dished or conical ends, fittings and filling allowance. The result is not a guaranteed working volume.
Results are rounded for display; assumptions and input accuracy limit actual precision.

Transfer time
Estimate the time needed to transfer a volume at constant flow.
Method and assumptions
t(min) = 60 × V(L)/Q(L/h)
Volume V in L and strictly positive flow Q in L/h. Excludes priming, stops and residual liquid. This is not the duration of a CIP cycle.
Results are rounded for display; assumptions and input accuracy limit actual precision.

Water heating: energy and ideal time
Estimate sensible energy and ideal heating time for a volume of water.
Method and assumptions
E(kWh) = V(L) × 1 × 4,19 × (T₂ − T₁)/3 600; t(min) = 60E/P(kW)
Liquid water from 0 to 95 °C: approximate density 1 kg/L and constant heat capacity 4.19 kJ/(kg·K). Constant net power P transferred to water. Excludes losses, heating the tank and pipes, boiling or other fluids: actual time may be longer. This is not an installation sizing tool.
Results are rounded for display; assumptions and input accuracy limit actual precision.
