Calculate x in the equation : `(velocity)^x = (pressire diff.)^(3//2)xx(density)^(-3//2)`

Explanation

`(pressure diff.)^(3//2)xx(density)^(-3//2)`
`= (ML^(-1) T^(-2))^(3//2)xx(ML^(-3))^(-3//2)`
`= M^(3//2) l^(-3//2) T^(-3)xx M^(-3//2) L^(+9//2)`
`= M^0 L^3 T^(-3) = (M^0 L^1 T^(-1))^2 = upsilon^3`
Hence x = 3
