Variables

Lift Force

The Lift Force, lifting force or simply lift is the sum of all the forces on a body that force it to move perpendicular to the direction of flow.

Symbol: F_L

Measurement: ForceUnit: N

Note: Value should be greater than 0.

Formulas to find Lift Force

Lift Coefficient

The Lift Coefficient is a dimensionless coefficient that relates the lift generated by a lifting body to the fluid density around the body, the fluid velocity and an associated reference area.

Symbol: C_L

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Lift Coefficient

Dynamic Pressure

Dynamic Pressure is simply a convenient name for the quantity which represents the decrease in the pressure due to the velocity of the fluid.

Symbol: q

Measurement: PressureUnit: Pa

Note: Value should be greater than 0.

Formulas to find Dynamic Pressure

Area For Flow

Area For Flow decreases velocity increases and vice versa. For subsonic flows, M < 1, the behavior resembles that for incompressible flows.

Symbol: A

Measurement: AreaUnit: m²

Note: Value should be greater than 0.

How to Evaluate Lift Force?

Lift Force evaluator uses Lift Force = Lift Coefficient*Dynamic Pressure*Area For Flow to evaluate the Lift Force, Lift Force formula is defined as a measure of the upward force exerted on an object as it moves through a fluid, such as air or water, at high velocities, particularly in the context of hypersonic flow parameters, where the interaction between the object and the fluid is critical. Lift Force is denoted by F_L symbol.

How to evaluate Lift Force using this online evaluator? To use this online evaluator for Lift Force, enter Lift Coefficient (C_L), Dynamic Pressure (q) & Area For Flow (A) and hit the calculate button.

FAQs on Lift Force

What is the formula to find Lift Force?

The formula of Lift Force is expressed as Lift Force = Lift Coefficient*Dynamic Pressure*Area For Flow. Here is an example- 550 = 0.021*10*50.

How to calculate Lift Force?

With Lift Coefficient (C_L), Dynamic Pressure (q) & Area For Flow (A) we can find Lift Force using the formula - Lift Force = Lift Coefficient*Dynamic Pressure*Area For Flow.

Can the Lift Force be negative?

No, the Lift Force, measured in Force cannot be negative.

Which unit is used to measure Lift Force?

Lift Force is usually measured using the Newton[N] for Force. Exanewton[N], Meganewton[N], Kilonewton[N] are the few other units in which Lift Force can be measured.
