Fluid flow momentum equation
WebStokes flow (named after George Gabriel Stokes), also named creeping flow or creeping motion, is a type of fluid flow where advective inertial forces are small compared with viscous forces. The Reynolds number is low, i.e. .This is a typical situation in flows where the fluid velocities are very slow, the viscosities are very large, or the length-scales of … WebIn this equation P_1 P 1 and P_2 P 2 represent the pressures of the fluid in volumes 1 and 2 respectively. The variables v_1 v1 and v_2 v2 represent the speeds of the fluid in volumes 1 and 2 respectively. And h_1 h1 and …
