1. ### Forced vortex

Hi, I am at a loss about getting this BC. if my coordinate is at the bottom of a tank which has some liquid in it and and I know that at free surface the pressure everywhere will be atmospheric, then how do I get the constant. I have trouble putting the pieces together. thanks in advance.
2. ### Forced vortex

Hi, Thank you again so much for your kind reply. I have also arrived to the final form of equation earlier which is a general solution which has a constant. Now, how do I find an exact solution of this equation, I mean, how can I define the constant, which will tell that, at any point on the...
3. ### Forced vortex

Hi, Thank you so much for your quick reply. I understand that integrating between two points can give the pressure difference between two points. Now, actually I am thinking of the surface of the forced vortex. On the concave surface of the forced vortex, at every point the pressure is going...
