2. (25 points) Find the force required to hold a cylindrical plug in place at the exit of a
horizontal water pipe. The pipe diameter is 0.25 m and the plug diameter is 0.2 m. The
flow rate is 1.5 $m^3/s$, and the upstream gauge pressure is 3.5 MPa. The momentum-flux
correction factor (B) is 1 everywhere.
