Worked Example
default_test
Given:
- mu_dyn = 0.001
- k_fluid = 0.598
- cp_fluid = 4182
Expected Result:
- pr_num = 6.9933110367893
Engineering Interpretation:
Under the given input conditions, the calculated result is: pr_num = 6.9933110367893.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
Formula / Method
pr_num = mu_dyn * cp_fluid / k_fluidpr_num.
