How do I convert between volumetric and mass flow rates?

Mass flow ṁ = ρ·Q. For water at 20°C (ρ = 998 kg/m³), Q = 1 L/s gives ṁ = 0.998 kg/s. For gases, density varies with P and T.

What is the difference between ACFM and SCFM?

ACFM (Actual CFM) is flow at actual conditions. SCFM (Standard CFM) corrects to 60°F, 14.696 psia reference. SCFM = ACFM × (P_actual/P_std) × (T_std/T_actual).

What is a barrel per day in pipeline terminology?

One barrel = 42 US gallons = 158.99 liters. 1 bbl/day = 0.00184 L/s. Commonly used for crude oil and petroleum product pipelines.

Volumetric Flow Rate Calculator

Calculate volumetric flow rate Q = A·V = π·D²/4·V. Convert between m³/s, L/s, GPM, CFM, and barrel/day. Mass flow rate ṁ = ρ·Q. Standard vs actual conditions for gas flow measurement.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)

σy — Normal Stress Y (MPa)

τxy — Shear Stress (MPa)

⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How to Use

Enter the values for the patient or scenario you are assessing. Calculate volumetric flow rate Q = A·V = π·D²/4·V. Convert between m³/s, L/s, GPM, CFM, and barrel/day. Mass flow rate ṁ = ρ·Q. Standard vs actual conditions for gas flow measurement. Use the volumetric flow rate result to inform your clinical assessment.
