Question

Bernoulli’s principle helps explain the hydraulics of brake fluid in cars. true or false

Answer 1

This statement is true.

Bernoulli’s principle explains the relation between the speed of the fluid and the pressure or potential energy of the fluid.
Bernoulli explained that an increase in the speed of a fluid is accompanied with a decrease in pressure and potential energy of the fluid.  

This principle can be applied to the hydraulics of brake fluid in cars. 

Answer 2

Explanation :

The principle behind Hydraulic brakes is Pascal's law.

According to Bernoulli's principle, the speed of a fluid depends inversely on the pressure or on the potential energy of the fluid.

Mathematically,

$P_1+\dfrac{1}{2}\rho v_1^2+\rho gh_1=P_2+\dfrac{1}{2}\rho v_2^2+\rho gh_2$

According to Pascal's law, there is an equal distribution of the pressure in the container having fluids i.e.

$P_1=P_2$

Hence, the given statement is false.
