WebJan 16, 2024 · Now, we take the curl of this equation and obtain: ∂ w → ∂ t = ∇ × ( v → × w →) + 1 ρ 2 ∇ ρ × ∇ p, Where, w → = ∇ × v → is the vorticity field. For incompressible fluids we have that ∇ ⋅ v → = 0 and the vorticity equation should become: ∂ w → ∂ t = ∇ × ( v → × w →). I don't understand how ∇ ⋅ ... WebNow ,rearranging our flow rate equation in terms of volume, our calculations are as follows: Q = V t, V = Q t, V = ( 500 m 3 s) ( 3600 s), V = 1.8 × 10 6 m 3. Flow rate is also calculated in terms of velocity and area. Q = v A, where v is velocity and A is the cross-sectional area. Flow rate has corresponding SI units of m 3 s; however, other ...
