## Homework Statement

The velocity field is known

ux=6x+8z*cos(a*t)

uy=3xz*sin(b*t)+2

uz=-6z

The fluid is incompressible.

I need to find the pressure gradient and the i have to determine if it's a turbulent flows, but at the moment i need help for the first question

## The Attempt at a Solution

I thought to use the pressure equation

div (grad(p)) = −div (div(vv))

but i should solve the problem analitically and talking with teacher he told me that this isn't the righ solution, obviously i cannot use the bernoulli equation because the fluid is viscous
