I’m trying to calculate the optimal rotational velocity to launch an object weighing 1.3G at 150fps. I want to know the best diameter to achieve that number when it’s spinning on a shaft that goes 42000rpm?

Is there an easy way to calculate the effects of Bernoulli’s principal on a fluid?

Is a longer spring more Efficient at producing power with work over time than a shorter spring of the same strength?
