Question

As the speed of a fluid increases, ____.

Answer 1

Answer:

a. the pressure decreases

Explanation:

If we assume here the flow of the fluid to be ideal flow such that there is no viscous loss in the fluid then in this case we can say that Bernoulli's theorem is valid here.

so here we can say

$P + \frac{1]{2}\rho v^2 = constant$

now here from above equation we can say that sum of pressure and kinetic energy of fluid will remain constant always

Now if speed of flow of the fluid is increased then to sum remain constant in ideal flow the pressure must have to decrease here.

so correct answer would be

a) the pressure decreases

Answer 2

The correct answer for the question that is being presented above is this one: "a. the pressure decreases." As the speed of a fluid increases, the pressure decreases." The relationship of the speed and the pressure is inversely proportional. As the pressure increases, the speed decreases.
