Question

Which will have more pressure at its base,water stored in a cylinder of radius r=1m,height=5m or r=0.5m,height=3m?

Answer 1

Hey.
Here is your answer.

As weight of water =dVg
so, pressure =dVg/πr^2
so, pressure=dπr^2hg/πr^2 as volume of cylinder=πr^2h and area if base is πr^2

so, pressure=dhg
so, we can see that pressure is directly proportional to h and us independent of r.
so as h=5 >h=3
so, cylinder with r=1m and height =5m will have more pressure.

Thanks.
