Non-streamlined objects such as bluff bodies and flat plates may also generate lift when moving relative to the fluid, but will have a higher drag coefficient dominated by pressure drag.

If the lift coefficient for a wing at a specified angle of attack is known ( or estimated using a method such as thin airfoil theory ), then the lift produced for specific flow conditions can be determined using the following equation:

* is the lift coefficient at the desired angle of attack, Mach number, and Reynolds number

For example, the phenomenon of flutter in aerodynamics occurs when an arbitrarily small displacement of an aircraft wing ( from its equilibrium ) results in an increase in the angle of attack of the wing on the air flow and a consequential increase in lift coefficient, leading to a still greater displacement.

A typical lift coefficient versus angle of attack curve.

This allows one to produce common curves such as lift coefficient versus angle of attack ( shown ).

* Critical angle of attack, in aerodynamics ; the angle of attack which produces the maximum lift coefficient

# Lift coefficient ( C < sub > L </ sub > or C < sub > Z </ sub >) ( Aerodynamics ) ( dimensionless )-Relates the lift generated by an airfoil with the dynamic pressure of the fluid flow around the airfoil, and the planform area of the airfoil.

If the angle of attack and velocity remain constant, an increase in the lift coefficient will result, which accounts for the " floating " effect.

In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.

The critical angle of attack is the angle of attack on the lift coefficient versus angle-of-attack curve at which the maximum lift coefficient occurs.

In this case, the wing can be flown at higher lift coefficient ( closer to stall ) to produce more overall lift.

Post stall, steady flight beyond the stalling angle ( where the coefficient of lift is largest ), requires engine thrust to replace lift as well as alternative controls to replace the loss of effectiveness of the ailerons.

) For a symmetric airfoil, as angle of attack and lift coefficient change, the center of pressure does not move.

For a conventionally cambered airfoil, the center of pressure lies a little behind the quarter-chord point at maximum lift coefficient ( large angle of attack ), but as lift coefficient reduces ( angle of attack reduces ) the center of pressure moves toward the rear.

When the lift coefficient is zero an airfoil is generating no lift but a conventionally cambered airfoil generates a nose-down pitching moment, so the location of the center of pressure is an infinite distance behind the airfoil.

A functor G: C → D is said to lift limits for a diagram F: J → C if whenever ( L, φ ) is a limit of GF there exists a limit ( L ′, φ ′) of F such that G ( L ′, φ ′)

C. S. Lewis argues that when talking about omnipotence, referencing " a rock so heavy that God cannot lift it " is nonsense just as much as referencing " a square circle "; that it is not logically coherent in terms of power to think that omnipotence includes the power to do the logically impossible.

To build the canal, the C & O Canal Company utilized a total of 74 lift locks that raised the canal from sea level at Georgetown to at Cumberland.

This decomposition separates the effect of the lift coefficient in the equation, obtaining two terms C < sub > D0 </ sub > and C < sub > Di </ sub >.

C < sub > D0 </ sub > is known as the parasitic drag coefficient and it is the base draft coefficient at zero lift.

C < sub > Di </ sub > is known as the induced drag coefficient and it is produced by the body lift.

: C < sub > L </ sub > = lift coefficient

However, one can lift a projective representation of G to a linear representation of a different group C, which will be a central extension of G. To understand this, note that GL ( V ) → PGL ( V ) is a central extension of PGL, meaning that the kernel is central ( in fact, is exactly the center of GL ).

At the point of minimum drag, C < sub > D, o </ sub > ( drag coefficient of aircraft when lift equals zero ) is equal to C < sub > D, i </ sub > ( induced drag coefficient, or coefficient of drag created by lift ).

: C < sub > L </ sub > is the lift coefficient at the desired angle of attack, Mach number, and Reynolds number.

On June 10, 2010 Baker Hughes announced an agreement to work with PetroChina Tarim Oilfield Co. to supply oilfield services, including both directional and vertical drilling systems, formation evaluation services, completion systems and artificial lift technology for wells drilled into foothills formations greater than 7, 500 meters ( 24, 600 feet ) deep with pressures greater than 20, 000 psi ( 1379 bar ) and bottomhole temperatures of approximately 160 ° C ( 320 ° F ).

Stem extensions have the nice property that any lift of a generating set of G is a generating set of C. If the group G is presented in terms of a free group F on a set of generators, and a normal subgroup R generated by a set of relations on the generators, so that G ≅ F / R, then the covering group itself can be presented in terms of F but with a smaller normal subgroup S, C ≅ F / S.

One other bridge spanned the C & D Canal before the lift bridge.

The pressure in chamber C will drop and the incoming pressure will lift the diaphragm thus opening the main valve.

Approximately 1 m < sup > 3 </ sup > of air at ambient pressure is required per tonne of lift.
