Consider a flow for which the velocity vector is:
Compute the mass-flow rate across a plane of area A that is perpendicular to the x axis and lies at x=3L. The fluid density is d.
I know that the mass-flow rate, M, is calculated by:
M=Double integration [d(u*n)]dA
I am having trouble setting up the integral though. I think that dA becomes dy dz but I'm not for sure what the limits will be for those.© BrainMass Inc. brainmass.com September 21, 2018, 5:54 am ad1c9bdddf - https://brainmass.com/engineering/mechanical-engineering/mass-flow-rate-115544
The solution computes the mass-flow rate across a plane.
