As Bernoulli Principle says, the fluid pressure decreases when speed increases. So if a river speeds up when it's narrowing down, the fluid pressure goes down.

What is bernoulli's princeiple?
If you mean Bernoulli's principle, it's the statement that an increase in the speed of a fluid produces a decrease in pressure and a decrease in the speed produces an increase in pressure.
Does speed increase or decrease as the pressure of a moving liquid increases?
for ideal fluid pv=nRT, so when pressure increase velocity decreases since vel. is inversly proportional to pressure....
How is fluid speed and fluid pressure related?
Fluid pressure decreases as speed increases. Bernoulli's principle states "as the speed of a moving fluid increases, it's pressure decreases.
How pressure changes as the velocity of a fluid increases?
If we assume that the fluid we are referring to is that of an ideal fluid (incompressible and non-viscous) and is undergoing a laminar flow, we can model this problem by Bernoulli's principle and equation. Bernoulli's principle states that if the above conditions are met, the energy density of a fluid must be a constant, fixed value. This means that if the velocity of a fluid increases, other factors must decrease for the energy density of a fluid must be conserved. Bernoulli's Equation is the sum of the magnitude of the pressure, kinetic energy and potential energy of a fluid is equal to a constant. Therefore, if a velocity of a fluid increases, the kinetic energy of the fluid increases. As a result, the pressure or the potential energy must decrease. Both or only one may change; the result is dependent on the situation.
Does air pressure increase or decrease as you go higher?
decrease
What is bernoulli's princeiple?
If you mean Bernoulli's principle, it's the statement that an increase in the speed of a fluid produces a decrease in pressure and a decrease in the speed produces an increase in pressure.
Do compressed oxygen in a pressurized tank show a decrease in fluid pressure?
burros
When you exert force on a fluid in a closed container does the pressure increase decrease or remain constant?
The pressure increases.
What is fluid gradient?
Usually a fluid gradient refers to the pressure gradient in any kind of fluid. It is a quantity that shows which direction and how fast the pressure changes around a location.
What does Bernoulli's principles states?
Bernoulli's principle states that an increase in the speed of a liquid results in a decrease in pressure, and a decrease in the speed of a liquid results in an increase in pressureBernoulli's Principle states that as the velocity of a fluid increases, the pressure exerted by that fluid decreases.
What is pressure loss?
decrease in pressure from one point in a pipe or a duct to another point downstream of the fluid flow. It is due to frictional forces on a fluid that flow through a pipe or a duct
Increased blood pressure would decrease the amount of fluid leaving the capillaries?
False, would increase the amount of fluid leaving the capillaries.
What is the effect of a fluid bolus on blood pressure and heart rate?
It will increase blood pressure by increasing volume. This will have a negate chromotropic effect and decrease HR.
Do skis increase or decrease pressure?
they decrease pressure

Can antibiotics decrease cervical fluid during pregnancy?
No, it cannot decrease cervical fluid
How would relaxing the smooth muscles in arteries affect blood pressure?
Blood pressure would decrease
