Wasn't sure if what I did was correct...still practising the topic itself

The quality of your exhibits is very poor, but, as best I could tell, your approach is on target. But I wish I could see a cleaner rendition of your momentum balance.

Sorry about that
I think it got messed up when it was uploading.

These are my cacluations for momentum

Im thinking that I was supposed to make the momentum in the y direction negative?

I still can't read it. Did you remember to include the pressure forces on the fluid entering and leaving?
What you're trying to do is a momentum balance on the fluid passing through the y. The force of the fluid on the y is then minus the force of the y on the fluid.
