Question $3(2$ points$)$

A horizontal reducer is installed to connect a $Di=90mm$ diameter pipe to a $Do=40$ mm diameter pipe as shown in figure below.

The velocity for the inlet is Vin $=2\frac{m}{s}$ and the velocity for the outlet is Vout $=8\frac{m}{s}$ The flow rate is $Q=21\mathrm{.}00\frac{L}{s}$ and the fluid density, rho is $980k\frac{g}{m^3}$

Find the Force in the $x$ direction if the inlet pressure is $n=360$kPa and the outlet pressure is Pout $=260$kPa

Answer Precision is to $0$ decimal places

Hide hint for Question $3$

Use the momentum equation between the inlet and the outlet.

Make use you take care of the directions for both the velocities and Pressures.

These can be both positive $(+)$ or negative $(-)$
