WebJul 21, 2015 · In this present work, the wall jet is assumed to be a uniform inlet velocity profile and the jet density is assumed to be atmosphere air density. The governing equations for two-dimensional and incompressible laminar flow, mass, and momentum equations were expressed in the finite difference conservation form as follows. Continuity Equation WebHere are two answers using notation: H =top surface of water, h =height of jet, d =distance traveled by jet. P r e s s u r e = ρ g ( H − h), Force on a droplet of area A and volume V is F = ρ g ( H − h) A. Assuming this force acts for some unit time t, speed at orifice exit is S = g ( H − h) A t / V.
