Question

A cylindrical float has a 10-in diameter and is 12 in long.What should be the specific weight of the float material if it isto have nine-tenths of its volume below the surface of a fluid witha specific gravity of 1.10? A cylindrical float has a 10-in diameter and is 12 in long.What should be the specific weight of the float material if it isto have nine-tenths of its volume below the surface of a fluid witha specific gravity of 1.10? A cylindrical float has a 10-in diameter and is 12 in long.What should be the specific weight of the float material if it isto have nine-tenths of its volume below the surface of a fluid witha specific gravity of 1.10?

Explanation / Answer

d = 10-in, L = 12 in, f = 1.10, find A = area of cross section, volume V = LA V = f*(9/10)V = 0.9f = 0.99
