Assume the bend of Problem 4.35 is a segment of a larger channel and lies in a horizontal plane. The inlet pressure is 170 \(\mathrm{kPa}\) absolute, and the outlet pressure is \(130 \mathrm{kPa}\) absolute. Find the force required to hold the bend in place.

Data From Problem 4.35

Transcribed Image Text:

4.35 Water enters a two-dimensional, square channel of constant width, h=75.5 mm, with uniform velocity, U. The channel makes a 90 bend that distorts the flow to produce the linear velocity profile shown at the exit, with Vmax = 2 Vmin. Evaluate Vmin, if U=7.5 m/s.
