WebDischarge coefficient. In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, [1] i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working ... WebJan 1, 1987 · The crack flow equations developed by Etheridge [1] have been verified over a wider range of parameters. ... have suggested an equation of the form 1 z Ca k RehDh + C where Cd is the discharge coefficient of the crack, Re,, is the Reynolds number based on the hydraulic diameter dal Dh, C is an empirical constant and k is an apparent …

Web6.1.31.1 Methods Defined Here. get() -> [opening data] Returns data for all Macroflo openings. Dictionary fields are: crack_flow_coefficient. Crack flow coefficient. … WebA crack flow coefficient was used to deal with inflow partitioned to cracks. A soil layer below tile drain with low saturated hydraulic conductivity was employed in simulating the experimental site, where most water was leaving the field through tile drain. Lateral subsurface flow was used to substitute for drainage. dolphins message board forum
WebDuring the hydraulically induced fracturing process (Lecampion et al., 2024; Morita et al., 1990; Zhao et al., 2024), regarding the crack width and fluid flow, there are three cases, as illustrated in Fig. 3 (a).In Case 1, as fluid is injected, the crack width increases gradually until the fracture initiates, which usually occurs at the initial stage of fluid injection or after … WebOct 31, 2024 · Cq = Cc ∙ [1/(1+Cc∙(a/h)] 0,5, in which head may change.Calculate the discharge related to the first trial hydraulic head and the first chosen discharge coefficient. If this discharge value ... WebHowever, an orifice gas discharge coefficient C is included to account for multi-dimensional effects and gas streamline contraction losses as the gas flows from the tank through the hole (Kayser, p. 1698; Shapiro, pp. 83-100). The gas flow equations assume that the velocity through the crack is much higher than the velocity in the pipe. dolphins match
