Question

The pressure exerted by a liquid column of depth 0.5 m on the base of its
container is 5000 Nm Find the density of the liquid
e Density of water is 1000 kg/m". What will be the volume of 35000 kg water?
​

Answer 1

Answer:

1020.4kg/m³

35m³

Explanation:

Given parameters:

Depth  = 0.5m

Pressure exerted  = 5000N/m²

Unknown = density of the liquid  = ?

Solution:

To find the density of this unknown liquid, we use the expression below:

       Pressure of liquid  = density x height x acceleration due to gravity

   5000 = density x 0.5 x 9.8

    Density  = 1020.4kg/m³

B.

Density of water  = 1000kg/m³

Mass of water  = 35000kg  

 Unknown:

Volume of water  = ?

Solution:

 The volume of water can be derived from the expression below:

   Volume  = $\frac{mass}{density}$  

  Volume  = $\frac{35000}{1000}$    = 35m³
