How it works
Use steady mass flow with the units stated beside the fields. This form solves for density; enter the known quantities in Mass flow rate, Volumetric flow rate.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Mass flow rate | 9 kg/s | Formula symbol: ṁ. Required unit: kg/s. Must be greater than zero. |
| Volumetric flow rate | 0.009000000000000001 m³/s | Formula symbol: Qᵥ. Required unit: m³/s. Must be greater than zero. |
Worked example
Show example inputs and results
This example is generated by the same calculation engine using the starting values in the form. Your own inputs produce your own result.
- Mass flow rate
- 9 kg/s
- Volumetric flow rate
- 0.009000000000000001 m³/s
Complete example results
- Density
- 1,000 kg/m³
Reading the result
The result solves for density from the entered quantities. Check the result unit and the formula conditions before using it.
Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
When can I use the density result?
This model uses positive magnitudes. Density and volumetric flow refer to the same section and are constant. Mass flow is kg/s; volume flow is m³/s.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
