Question

write notes on density and pressure of water​

Answer 1

Explanation:

Water pressure is the amount of force per unit area that water exerts, say, on the container it's in or on a submerged object. The pressure of water that's not moving depends on the depth. It's given by the formula. P = density * g * depth.

I hope it will help u ⭐️

can anyone plz follow me....?

Answer 2

When density decreases, the pressure decreases. Since the density is constant, the weight can be calculated using the density: w=mg=ρVg=ρAhg. The pressure at the bottom of the container is therefore equal to atmospheric pressure added to the weight of the fluid divided by the area: p=p0+ρAhgA=p0+ρhg.

What is density and pressure?⤵

Density is the mass per unit volume of a substance or object, defined as ρ=m/V. ρ = m / V . The SI unit of density is kg/m3. kg/m 3 . Pressure is the force per unit perpendicular area over which the force is applied, p=F/A.
