Torricelli Efflux Speed Calculator
Estimates ideal speed from a small opening below a free surface. Changing an entry updates the answer and the substitution line.

Efflux speed
Set up v = √(2gh)
Begin with v = √(2gh) and identify the sought quantity before substituting. The sample entries give a concrete calculation that can be repeated by hand.
For torricelli efflux speed, keep v = √(2gh) symbolic through the unit check; substitute only after the numerator, denominator, and powers are settled.
What the number describes
Estimates ideal speed from a small opening below a free surface. The inputs describe liquid head, gravitational acceleration, and the reported unit is m/s.
The opening is assumed small relative to the tank so free-surface speed is negligible.
On the torricelli efflux speed page, each number stays beside its physical unit. That pairing matters because a converted value placed in an unconverted field can look plausible while changing the model.
A dimensional check before trusting the number
Reduce the units in v = √(2gh); the surviving dimension must agree with m/s. If it does not, the arithmetic should not be accepted even when the displayed number is finite.
Then vary one measured input by ten percent and predict whether efflux speed should rise, fall, or remain unchanged. That sensitivity test is independent of merely repeating the same keystrokes.
A reproducible Torricelli Efflux Speed example
The starting example uses Liquid head = 4 m; Gravitational acceleration = 9.80665 m/s². Entering those values provides a baseline before testing a different physical condition.
After calculating, rearrange v = √(2gh) for one supplied quantity and see whether it returns the original entry. This reverse check is especially helpful when powers, ratios, or reference values are present.
Carrying efflux speed into later work
Carry extra digits for efflux speed only while another operation follows. Final precision should reflect the least certain measurement used on the torricelli efflux speed page.
Record the formula, units, geometry, and material state with efflux speed. A bare number cannot reveal whether density, pressure reference, flow area, or operating condition was interpreted correctly.
Assumptions for Torricelli Efflux Speed
The calculation assumes steady incompressible flow and the geometry printed beside the inputs. Storage, leakage, cavitation, or an omitted loss coefficient requires a broader balance before accepting efflux speed.
Before reusing efflux speed, decide whether the omitted effects are small enough for the intended comparison.

Questions about Torricelli Efflux Speed
What does the efflux speed represent?
It is the output of v = √(2gh) for the field definitions and units printed on the torricelli efflux speed page.
How can I check the efflux speed?
Rearrange v = √(2gh) to recover one input, and independently confirm that the remaining dimension reduces to m/s.
Must all entries use the displayed units?
Yes. Convert every measurement to the unit beside its field before applying the torricelli efflux speed relationship.
