Pipeline

How much percent has the pipe cross-section area changed (reduced) if the circular shape is changed to square with the same perimeter?

Final Answer:

p =  21.46 %

Step-by-step explanation:

p = 100 S1S1S2 p = 100(1 S1 S2) p = 100(1  π r2 a2) p = 100(1  π r2 a2)  o = 2 π r = 4 a π r = 2 a  p = 100(1  π (2a/π)2 a2) p = 100(1  π 4/π2 1)  p=100 (14π)=100 (143.1416)=21.46%
