Chapter 14: Q. 2 (page 383)

Rank in order, from largest to smallest, the pressures at a, b, and c in FIGURE Q14.2. Explain.

Short Answer

Expert verified

The pressure in the decreasing order as Pb > Pc> Pa

Step by step solution

01

Given information

Three points (a,b and c) are given in the tank with different height filled with liquid.

02

Explanation

We know that the pressure exert by a liquid in tank depends on height and density of the liquid.

They are related as

P = hρg + Atmospheric pressure.

Where

P = pressure

h = height of liquid column above point

ρ = density of liquid

g = gravitational acceleration

Here we can see pressure (P) depends on the height (h) as density is same.

From the figure we can see

hb > hc > ha

So the pressure will be in the same order

Pb > Pc > Pa
