  2. Center of pressure (fluid mechanics) - Wikipedia

    en.wikipedia.org/wiki/Center_of_pressure_(fluid...

    Center of pressure is used in sailboat design to represent the position on a sail where the aerodynamic force is concentrated.. The relationship of the aerodynamic center of pressure on the sails to the hydrodynamic center of pressure (referred to as the center of lateral resistance) on the hull determines the behavior of the boat in the wind.

    Pressure used in boilers of steam locomotives [citation needed] 1.1 MPa 162 psi Pressure of an average human bite [citation needed] 2.8–8.3 MPa 400–1,200 psi Pressure of carbon dioxide propellant in a paintball gun [64] 5 MPa 700 psi Water pressure of the output of a coin-operated car wash spray nozzle [58] 5 MPa 700 psi

  4. Forces on sails - Wikipedia

    en.wikipedia.org/wiki/Forces_on_sails

    Pressure differences result from the normal force per unit area on the sail from the air passing around it. The lift force results from the average pressure on the windward surface of the sail being higher than the average pressure on the leeward side. [1] These pressure differences arise in conjunction with the curved air flow.

  5. Center of pressure (terrestrial locomotion) - Wikipedia

    en.wikipedia.org/wiki/Center_of_pressure...

    The center of pressure is not a static outcome measure. For instance, during human walking, the center of pressure is near the heel at the time of heelstrike and moves anteriorly throughout the step, being located near the toes at toe-off. For this reason, analysis of the center of pressure will need to take into account the dynamic nature of ...

  7. Aerodynamic center - Wikipedia

    en.wikipedia.org/wiki/Aerodynamic_center

    The aerodynamic center is the point at which the pitching moment coefficient for the airfoil does not vary with lift coefficient (i.e. angle of attack), making analysis simpler. [ 1 ] d C m d C L = 0 {\displaystyle {dC_{m} \over dC_{L}}=0} where C L {\displaystyle C_{L}} is the aircraft lift coefficient .

  8. Pressure coefficient - Wikipedia

    en.wikipedia.org/wiki/Pressure_coefficient

    This pressure distribution is simply the pressure at all points around an airfoil. Typically, graphs of these distributions are drawn so that negative numbers are higher on the graph, as the C p {\displaystyle C_{p}} for the upper surface of the airfoil will usually be farther below zero and will hence be the top line on the graph.

  9. Center of gravity of an aircraft - Wikipedia

    en.wikipedia.org/wiki/Center_of_gravity_of_an...

    The center of gravity (CG) of an aircraft is the point over which the aircraft would balance. [1] Its position is calculated after supporting the aircraft on at least two sets of weighing scales or load cells and noting the weight shown on each set of scales or load cells. The center of gravity affects the stability of the aircraft.
