Answer:
umax = 0.1259ft/s
Explanation:
Given:
•Distance between plates, B = 0.01ft
•Pressure difference decrease,
•Fluid viscosity, u = 10^-³lbf-s/ft²
Specific gravity, S = 0.80
Max velocity in the z-direction will be:
Substituting for h in the first equation, we have:
= -0.20192
Substituting dh/dz value in the first equation (umax), we have:
umax = 0.1259ft/s
