Aclosed column of water has a diameter of 1.6 m and a depth of 8 m. how much pressure is at the bottom of the column? the acceleration of gravity is 9.8 n/kg . answer in units of pa. 002 (part 2 of 3) 10.0 points what is the weight of this column of water? answer in units of n.

This question involves the concepts of density, weight, and pressure of a column of a liquid.

a) The pressure at the bottom of the column is "78400 Pa".

b) The weight of this column of water is "157632.55 N".

a)

The pressure at the bottom of the water column is given as follows:

where,

P = Pressure at the bottom = ?

= density of water = 1000 kg/m³

g = acceleration due to gravity = 9.8 m/s²

h = depth of water column = 8 m

Therefore,

P = 78400 Pa = 78.4 KPa

b)

Now, the weight of this column of water can be calculated as follows:

where,

W = Weight = ?

V = Volume = = 16.1 m³

Therefore,

W = 157632.55 N = 157.6 KN

The attached picture shows the concept of density.

P = 80 KPa

Wt== 160. 84 KN

Explanation:

Given that

Depth ,h= 8 m

Diameter ,d= 1.6 m

g= 9.8 N/kg

We know that

Density of water ,ρ=1000 kg/m³

Pressure P

P = ρ g h

P =1000 x 10 x 8

P = 80 KPa

The force on the bottom F

F= P.A

A= π/4 d²

A= 0.785 x 1.6² m²

A= 2.01 m²

F= P.A

F= 80 x 2.01 KN

F= 160.84 KN

So the wight of the column = 160. 84 KN
