The hydrostatic pressure term in the Bernoulli equation (ρgz) decreases with fluid depth. Why?
Bernoulli Equation (multiplied by density ρ to give us pressure units):
The Attempt at a Solution
In the hydrostatics chapter in my book, hydrostatic pressure, ρgh, increases with depth. However, in the Bernoulli equation, the hydrostatic pressure term ρgz decreases with depth.
Is this just because we're selecting a coordinate system where the vertical direction faces up instead of down?
What physical significance does this have?
