V_p2 = sqrt(2*[g]*h_venturi+V₁^2)
This formula uses 1 Constants, 1 Functions, 3 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Velocity at Point 2 - (Measured in Meter per Second) - Velocity at Point 2 defines the direction of the movement of the body or the object.
Venturi Head - (Measured in Meter) - Venturi headt is the difference between pressure head at inlet and pressure head at the throat.
Velocity at Point 1 - (Measured in Meter per Second) - Velocity at Point 1 is the velocity of fluid passing through point 1 in flow.

STEP 1: Convert Input(s) to Base Unit

Venturi Head: 24 Millimeter --> 0.024 Meter (Check conversion here)
Velocity at Point 1: 58.03 Meter per Second --> 58.03 Meter per Second No Conversion Required
