i'm a little bit confused.(adsbygoogle = window.adsbygoogle || []).push({});

if the velocity potential Φ = Φ(x,y,t).

and it says Φ satifies laplace's equation.

does that mean ∂²Φ/∂x² + ∂²Φ/∂y² = 0

or

∂²Φ/∂x² + ∂²Φ/∂y² + ∂²Φ/∂t² = 0.

does the time variable get included??

i'm thinking it isn't but i'm not exactly sure.
