WebDynamic pressure is the kinetic energy per unit volume of a fluid in movement. Energy and Hydraulic Grade Line . The hydraulic grade line and the energy line are graphical presentations of the Bernoulli equation. Energy Equation - Pressure Loss vs. Head Loss . Calculate pressure loss - or head loss - in ducts, pipes or tubes. Equations in Fluid ... WebFor pressure drop larger than the critical pressure drop the flow is choked. The flow coefficient can be calculated as: Cv = q [SG (T + 460)]1/2/ (FL 834) pi (5) where. q = free gas per hour, standard cubic feet per hour (Cu.ft/h) SG = upstream specific gravity of flowing gas gas relative to air (SG = 1.0) at 14.7 psia and 60oF. WebPressure Head The ratio between developed pressure at different temperatures can be expressed as: dpo / dpr = (273 + to) / (273 + tr) (2) or dpo = dpr (273 + to) / (273 + tr) (2b) where dpr = reference pressure … gaytanfam hotmail.com
