Question

Bernoulli's principle describes the relationship between which two values of a fluid?

A. Velocity and depth
B. Buoyant force and weight displaced
C. Pressure and depth
D. Velocity and pressure

Answer 1

D. Velocity and pressure

Step-by-step explanation:

Bernoulli's principle relates the pressure and the velocity of a fluid with the following equation:

`p+(1)/(2)\rho v^2 = const.`

where

p is the pressure

`\rho` is the fluid density

v is the velocity of the fluid

According to this relationship, we see that if the pressure in the fluid increases, the velocity decreases, and vice-versa.

From the equation, we also notice that the correct answer is

D. Velocity and pressure

since these are the two quantities involved in the equation.
