Apipe originally has a radius of 1.25m. it narrows down to a radius of 0.55m. if the original force in the big pipe is 72n, what is the force in the narrow part of the pipe?

Use direct proportionality: If 1.25 m = 72 N, then 0.55 m = y

0.55 m × 72 = 39.6.

39.6÷1,25 gives you your answer which is 31.68 N.
