$Assertion :$ The velocity of flow of a liquid is smaller when pressure is larger and vice-versa.
$Reason :$ According to Bernoulli’s theorem, for the stream line flow of an ideal liquid, the total energy per unit mass remains constant.

According to Bernoulli's theorem, for the stream line flow of an ideal liquid, the total energy per unit mass is constant.

That is $P+\frac{\rho v^{2}}{2}+\rho g h=C$

velocity of liquid depends on pressure as well as potential height available.

    At shallow depth $h$, the pressure in the ocean is simply given by $P = P_0 + \rho gh$, in which $\rho$ is the density of water and $P_0$ is the air pressure. As we go deeper, the high pressure causes the water to compress and become denser. Which of the following sketches illustrates the correct dependence of the pressure on the depth $h$ ?
