1. The problem statement, all variables and given/known data A 90 degree reducing bend has an inlet diameter of 4 in. and an outlet diameter of 2 in. If water enters the bend at a pressure of 40 psig and a flow of 500 gpm, calculate the force (net magnitude and direction) exerted on the supports that hold the bend in lace. The loss coefficient (number of velocity heads lost due to fluid frictional drag) is 0.75 based on the highest velocity in the bend. 2. Relevant equations 3. The attempt at a solution For this problem, I am having troubles finding the pressure at the outlet, as well as the force of gravity in my first momentum balance in the y-direction since I don't know the volume of the pipe. Also, I'm not sure which direction the drag force should go, I've seen it in the lecture notes as being positive in a situation where water was flowing up a pipe, which seems odd to me, I imagine it would oppose motion similar to friction.
