Hi all!
Possible variables could be the shape of the spoon, the velocity of the jet, the angle of the spoon, the angle of the jet, the angle of contact, where contact with the spoon is made, the turblent or laminar nature of the water jet, the viscoscity of the water, the compresiblity, heat of the water and the force of gravity (there is probably more)
Thank you for taking the time to read this.
:dubious: Is this homework?
Do we know the function that describes the shape of the spoon?

Here’s a paper on a laminar jet impinging on a flat surface. Equations will be pretty similar for the spoon surface. You will need CFD software to predict the spread of water.
If it is … then we have the most sadistic professor in the world …
The problem described in the OP would not be out of place in a graduate-level fluid mechanics course.

It sprays all over the kitchen.
Kitchen counter physics … thanks for taking one for the team …

I’m not able to recall *all *the details of the formula at this moment, but I’m pretty sure the correct answer given the OP’s inputs will be 42.

I have the proper information at hand, but first I need to know if the spoon is bowl side up (traditional) or bowl side down (Perkins transformation).
The viscosity and compressibility of water and the force of gravity are variables ? Aren’t those pretty invariable?

The first two vary a lot depending on temperature. Like say above 100C or below 0C vs somewhere in between.
The latter not so much unless we’re pouring on the Moon or something.
More importantly, is it a runcible spoon?

If it’s a spork you need to separately deal with the flow around and between each tine. Everything’s better with sporks.
