The answer is one of the options below please solve carefully and circle the correct option Please write clear .

This is a practice problem for an upcoming test, but I'm not really sure which direction to solve it in. If I use a basic pressure equation do I have to do iterations? Cause we should be able to take a ratio of flow in both pipes. Any information on the direction of how to solve this problem will be extremely helpful, as well as solving it.
