About This Tool
Hydraulic Radius Calculator helps you the hydraulic radius calculator finds the wetted perimeter and hydraulic radius for five different channel shapes without leaving the browser.
The hydraulic radius calculator finds the wetted perimeter and hydraulic radius for five different channel shapes.
This page opens with a focused preset flow. Keep ratio type set to part-to-part.
What This Tool Does
The hydraulic radius calculator is built for people who want a fast answer and a clearer understanding of what affects the final output.
It works best when you enter realistic values for Ratio Type, Part A, Part B. If the tool includes select boxes or toggles, choose the scenario that matches your use case before you calculate.
Variables and Inputs
Ratio Type
Choose the option that matches your use case; this field is required; Required. Choose the ratio type option that matches your calculation. Default: part-to-part..
Part A
Enter a numeric value; this field is required; Required. Enter the part a value..
Part B
Enter a numeric value; this field is required; Required. Enter the part b value..
Calculation Modes and Options
Ratio Type
Ratio Type changes how the calculator behaves. Available choices: part-to-part, part-to-whole.
How It Works
- Keep ratio type set to part-to-part.
- Enter Ratio Type, Part A, Part B in the calculator fields.
- Review the required options and units before running the calculation.
- Click Calculate to generate the result instantly from the current inputs.
Common Scenarios
Quick hydraulic radius calculator checks
Use this when you need a fast answer for homework, planning, estimation, verification, or daily work involving Ratio Type, Part A, Part B.
Compare nearby scenarios
Change one input at a time to see which value has the strongest effect on the result and to sanity-check your assumptions.
Examples
Worked examples help visitors sanity-check the calculator before relying on the result in a real workflow.
Basic hydraulic radius calculator example
Run a straightforward example first so you can see how the hydraulic radius calculator responds before trying edge cases.
- Keep Ratio Type set to part-to-part.
- Enter a sample value for Part A.
- Enter a sample value for Part B.
Expected outcome: Review the calculated output and note which input changes the result the most.
Compare two scenarios
Run the calculator once with baseline values, then change one important input and calculate again.
- Use your first set of values as a baseline.
- Change one key input only and rerun the calculation.
- Compare the difference in the result to understand sensitivity.
Expected outcome: This comparison helps explain which field has the strongest impact on the final answer.
Common Input Mistakes
- Check units before you calculate. Mixed units are one of the most common reasons a correct formula produces the wrong answer.
- Fill the required fields first. Optional fields should refine the result, not replace the core inputs.
- Confirm the selected mode before rerunning the calculator. A different option can change the interpretation of the same numeric inputs.
