Hydrodynamic force on an elastic and slender cylinder

[franknguyen]

Hello. Im new here. I would like to know some practical equation to calculate hydordynamic force on elastic and slender cylinder. I have a 2 meter long elastic cable with submerged in a water tank. Water in the tank is rotated at velocity v. A xy table is attached at the top end of the cable so I would like to know the hydrodynamic force on the calble in order to select motor required torque.

franknguyen, I moved your post here to the physics section, where it will get the attention you need.
