It's about this Equation:</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="DG_8871348_1-1622214540624.png" style="width: 400px;"><img src="https://www.ptcusercommunity.com/t5/image/serverpage/image-id/42191i86985EA4DA8A439E/image-size/medium?v=v2&amp;px=400" role="button" title="DG_8871348_1-1622214540624.png" alt="DG_8871348_1-1622214540624.png" /></span></P> <P>&nbsp;</P> <P>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.<BR /><BR />Pleas can you help me out with this Problem?<BR /><BR />Thenks a lot&nbsp;<span class="lia-unicode-emoji" title=":smiling_face_with_sunglasses:">😎</span></P> Fri, 28 May 2021 15:14:36 GMT https://www.ptcusercommunity.com/t5/Mathcad/How-to-solve-an-Equation-for-Hydrodynamics/m-p/731562#M196098 DG_8871348 2021-05-28T15:14:36Z https://www.ptcusercommunity.com/t5/Mathcad/How-to-solve-an-Equation-for-Hydrodynamics/m-p/731563#M196099 <P>Please attach your worksheet so we can see what was going wrong.</P> <P>&nbsp;</P> <P>The symbolic solve command should probably work OK.</P> <P>But as all other variables are defined, I would suggest using a numeric solve block (with "find").</P> <P>&nbsp;</P> Fri, 28 May 2021 15:17:46 GMT https://www.ptcusercommunity.com/t5/Mathcad/How-to-solve-an-Equation-for-Hydrodynamics/m-p/731563#M196099 Werner_E 2021-05-28T15:17:46Z https://www.ptcusercommunity.com/t5/Mathcad/How-to-solve-an-Equation-for-Hydrodynamics/m-p/731567#M196100 <P>Thx a Lot for the fast Reply!&nbsp;<BR /><BR />The File of this work is now attached. ...
