You so badly want to say F=mv that when I told you it's wrong you threw out the baby with the bathwater.

F=ma can predict the force the mass applies to the pipe.

But you can't use F=ma unless you know what acceleration means. You don't, so that formula is useless to you.

Wait! Maybe there is hope! Here you show you understand that the object is accelerating through the turn. I don't know why you changed your mind in the last message. This acceleration is how you can find the force. Which I think you also calculated!

the mass that is passing through the turn is undergoing centripetal acceleration , this acceleration is toward the center of the turn , not away from the center of the turn.
