How does the Nozzle Flow Calculator work?

Apply Bernoulli equation with contraction coefficient Then: Ideal: V = √(2gh), Actual: V = C_d × √(2gh) Then: Discharge: Q = C_d × A × V.

Can you give an example of how to use the Nozzle Flow Calculator?

Example: Input h = 5 m head, A = 10 mm², C_d = 0.6 (typical) gives a result of V ≈ 5.4 m/s, Q ≈ 0.054 L/s (Orifice discharge).

Is the Nozzle Flow Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
