The Energy Grade Line, also called the Energy Line (EL), is a plot of the Bernoulli equation or the sum of three terms in the work-energy equation. The EL is equal to the sum of the fluid's velocity head, the pressure, and the elevation head. EL = (V²/2g) + (p/γ) + h...
The surge pressure wave travels upstream and is reflected downstream, oscillating back and forth until its energy is dissipated in pipe wall friction. The amplitude of the surge wave, or the magnitude of the pressure surge Psurge, is a function of the change in velocity and the steepness of ...
The effect of water pressure in a pipe on the rate of leakage from leak openings in the pipe is one of the main factors influencing leakage that is still not understood sufficiently. In this study, the behaviours of different types of leak openings (round holes and longitudinal and ...
Example The volume rate of flow through a pipe can be determined by means of a flow nozzle located in the pipe as shown in Figure. The nozzle creates a pressure drop, pA – pB, along the pipe which is related to the flow rate through the equation, Q = K(pA – pB)1/2, where K...

Finally, we compare the present results with those of a continuous five-equation model, and obtain very good agreement. 展开 关键词: Theoretical or Mathematical/ numerical analysis pipe flow shock waves two-phase flow/ discrete-equation multiphase model discrete-equation two-pressure two-phase ...
Calculation of pressure drop caused by friction in circular pipes To determine the fluid (liquid or gas) pressure drop along a pipe or pipe component, the following calculations, in the following order.Equation Reynolds Number:Re = ω D / v Re = ρ v l / µ Re = ω l / v Where...
In addition, a separate evaluation of the momentum equation is carried out to investigate the effect of the accelerational pressure gradient component on the magnitude of the total pressure gradient. Rheometer testing was performed to obtain measurements required for the proposed model. In addition, ...
