Use this construction calculation for preliminary quantity, geometry, material, load, or coverage planning when dimensions and units have been measured consistently.

Volumetric flow (L/min)

Required number input.

Pressure drop (Pa)

Required number input.

Fluid density (kg/m³)

Required number input.

Discharge coefficient

Required number input.

Infer equivalent circular spray-tip orifice diameter from measured volumetric flow, pressure drop, fluid density, and discharge coefficient. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Equivalent orifice diameter (mm)

The resulting equivalent orifice diameter returned as a number.

• A quantity estimate or simplified engineering formula is not a building-code check, stamped design, manufacturer approval, or site inspection. Material properties, tolerances, waste, moisture, workmanship, loads, local conditions, and code requirements can change the result.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify dimensions on site, use current product data and local code requirements, include an explicit waste or safety allowance where appropriate, and obtain qualified structural, electrical, plumbing, or geotechnical review when required.

• Rebar Weight Per Foot

  Compute steel reinforcing-bar mass per foot from nominal circular diameter and supplied steel density.

• Concrete Formwork Pressure

  Hydrostatic upper-bound fresh-concrete pressure at a chosen depth from density and gravity; actual placement-pressure rules may differ.

• Concrete Yield

  Calculate fresh concrete batch yield as total batch mass divided by measured fresh density, both from the same batch.
