How to solve an Equation for Hydrodynamics

Hello, 

Today I made my work for Hydrodynamics. It's about this Equation:

DG_8871348_1-1622214540624.png

 

Every Variable except h2 is calculated before and so I'm looking for h2. I have no idea how this could work, the solve function does not work.

Pleas can you help me out with this Problem?

Thenks a lot 😎

Here is one way to solve it:

(Note that a symbolic solution is not found,

I guess because the order of the function is too high.)

 

Success!

Please attach your worksheet so we can see what was going wrong.

 

The symbolic solve command should probably work OK.

But as all other variables are defined, I would suggest using a numeric solve block (with "find").

Thank you very much! 😎

Solved using Prime 4.0 Express.  Openable in any later version.

 

Express will not calculate solve blocks, but the root function will work.
