@MarkE (or anyone that know's)
I have a question for you regarding my (rough)sketch below.Now i could set up an experiment myself,but time and cash are short in supply,as i need what i have of both to build the next setup-demo.

If we have two jets of water coming from two nozzles,and we direct those jets into each other at right angles(say an inch from the nozzles),using just jet A as an example,will jet B cause jet nozzle A to be pushed in direction A or direction B,or will there be no force applied to the nozzle itself at all

Once the water is free of each nozzle, but for some surface tension it goes on its way. Surface tension can transmit some force back up the stream, pushing the A nozzle leftward away from the B nozzle. The faster the stream from A the stronger the effect.

Being that surface tension is very weak,can we say that the force placed on nozzle A from the jet of water from nozzle B will be very weak?
What % of the 40 psi would you say is placed on nozzle A from jet B?.

It depends on the velocity of the water leaving the A nozzle. If the A nozzle is just dripping then virtually no force transmits back to the nozzle. If the velocity out the A nozzle is very high then you could get a decent percentage of the force that acts on the A stream to transmit to the A nozzle.

It would be 40 psi constant flow preasure, from both A and B nozzel,which are 1/2 inch nozzle's.
Would you think it would be more than 10% of the 40 psi that acts upon nozzel A-that seems to be a generous amount to me.

OK Mark-one more question.
In the slightly modified sketch below,i have added a green arrow. If water jet B is hitting water jet A,would this increase the force(in the direction of the green arrow)on nozzle B,or would the force on nozzle B be the same as if it wasnt hitting water jet A. Both jets of water intersect each other 1 inch from either nozzle.
