Description
Return impeller tip and angular speeds.
Physical process calculations combine supplied geometry, material properties and pressure or gas-state conventions. A density scaling, ideal-gas correction or vessel-volume term can be dimensionally consistent without verifying the actual fluid state, flow regime or equipment suitability.
Return impeller tip and angular speeds.
When to use this tool
Use Agitation Impeller Tip Speed Term when evaluating the stated geometric, fluid-property or gas-state term.
How to use the tool and how it works
- Enter diameter, revolutionsPerSecond. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read tipSpeed, angularSpeed. Use the output convention below.
Return impeller tip and angular speeds. Require diameter/revolutionsPerSecond >= 0; tipSpeed = pi*diameter*revolutionsPerSecond, angularSpeed = 2*pi*revolutionsPerSecond.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| diameter | Diameter | Required. Finite number; minimum 0. |
| revolutionsPerSecond | Revolutions Per Second | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| tipSpeed | Tip Speed | Required. Finite number. |
| angularSpeed | Angular Speed | Required. Finite number. |

}Limitations and assumptions
- Diameter units determine length/second; this does not establish mixing adequacy, shear exposure or mechanical safety.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified geometry and state-specific material data with an appropriate full engineering model for actual flow, storage or equipment design.
