Answer:
376966.991 Joules
Explanation:
Given that :
the height = 12 m
Let assume the tank have a thickness = dh
The radius of the tank by using the concept of similar triangle is :
The area of the tank =
The area of the tank =
The area of the tank =
The volume of the tank is = area × thickness
=
Weight of the element =
where;
= density of water ; which is given as 10000 N/m³
So;
Weight of the element =
Weight of the element =
However; the work required to pump this water = weight × height rise
where the height rise = 12 - h
the work required to pump this water = (12 - h)
the work required to pump this water =
We can determine the total workdone by integrating the work required to pump this water
SO;
Workdone =
=
=
=
=
=
= 376966.991 Joules
The pressure needed : 800 kPa
<h3>Further explanation</h3>Given
V₁ = 0.4 m³
P₁ = 100 kPa
T₁ = 20 + 273 = 293 K
V₂ = 0.05 m³
T₂ = T₁ = 293 K
Required
The final pressure(P₂)
Solution
Boyle's Law
At a fixed temperature, the gas volume is inversely proportional to the pressure applied
Input the value :
P₂=P₁V₁/V₂
P₂=100 x 0.4 / 0.05
P₂=800 kPa
