Pressure Drop

Pressure drop is defined as the difference in pressure between two points of a fluid carrying network. Pressure drop occurs with frictional forces, caused by the resistance to flow, on a fluid as it flows through the tube. The main determinants of resistance to fluid flow are fluid velocity through the pipe and fluid viscosity. Pressure drop increases proportional to the frictional shear forces within the piping network. A piping network containing a high relative roughness rating as well as many pipe fittings and joints, tube convergence, divergence, turns, surface roughness and other physical properties will affect the pressure drop. High flow velocities and / or high fluid viscosities result in a larger pressure drop across a section of pipe or a valve or elbow. Low velocity will result in lower or no pressure drop.

Famous quotes containing the words pressure and/or drop:

    Amid the pressure of great events, a general principle gives no help.
    Georg Wilhelm Friedrich Hegel (1770–1831)

    As easy mayst thou fall
    A drop of water in the breaking gulf,
    And take unmingled thence that drop again,
    Without addition or diminishing,
    As take from me thyself and not me too.
    William Shakespeare (1564–1616)
