Velocity of a liquid

I am trying to determine the velocity of a liquid. The density of the liquid is .885 g/cm3. The pressure at which it is being forced is 17236.89 kpa. What else do I need to know? I am looking for a formula to help me in other calculations with different pressures and densities. Thanks in advance for any help.

I assume it is being forced out of a nozzle or hole at that pressure. (Is that the total pressure or pressure above atmospheric?) The main other detail you need is the area of the hole/nozzle, though there is a difference between the measured area and the 'effective' area. That difference can depend on the internal geometry of the container.

Yes it is being sprayed from a nozzle in this case which is .16mm per hole and a total of 8 holes. The pressure is total.

Correction, you don't need the area - was thinking of a different problem.
Pressure P, velocity V, density D, area A. Power = P.A.V = A.V.D.(V2/2), V2 = 2P/D.
