I agree no pressure thrust but for a curved hose the braid angle will be different from the inside to the outside of the curved portion of the hose. So I would expect a straightening moment to generate restraining support forces as a result of the pressure in the hose.
How can I determine the forces and moments applied to a flexible curved hose, steel braided type, subjected to pressure, 4000psi approx 1-1.5 inch diameter? The forces and moments are from restraining supports at each end of the hose and/or intermediate hose supports.
