NiCuZn / Engineering tools
Free calculators for early sizing.
Quick, transparent calculations for chemical and process engineers. Every tool shows its method, so you can check the numbers.
Pump power and head
Differential head, hydraulic and shaft power, a standard motor size and NPSH available.
Open calculatorHeat exchanger area (LMTD)
Duty, log mean temperature difference, required area and cold-side flow.
Open calculatorHorizontal drum sizing
Diameter and length from liquid hold-up, with a Souders–Brown vapour check.
Open calculatorLine sizing and pressure drop
Velocity, Reynolds number, friction factor and pressure drop for every Schedule 40 size.
Open calculatorTank volume and level
Total and partial volume for horizontal or vertical tanks with dished heads, plus a level table.
Open calculatorControl valve Cv (liquids)
Required Cv and Kv with a choked-flow and cavitation check.
Open calculatorOrifice plate flow (liquids)
Flow from differential pressure, β ratio and permanent pressure loss for a sharp-edged plate.
Open calculatorPipe insulation heat loss
Heat loss, surface temperature, saving against bare pipe and annual energy.
Open calculatorUnit converter
Pressure, temperature, flow, power, energy and physical properties across SI, metric and US units.
Open calculatorResults are preliminary estimates for early engineering. Check them against your design basis, standards and vendor data. New to a term? See the process engineering glossary.
BLACK OWL EARLY ACCESS
Size equipment from your own balance.
In Black Owl, sizing works from the process flow diagram in the same project as the material balance.
