Transcribed Image Text:**Section 5.2.1 Linear Momentum—Uniform Flow**
(Refer to Lab Problems 5.98, 5.99, 5.100, and 5.101)
**Problem 5.22**
Exhaust (assumed to have the properties of standard air) leaves a 4-ft-diameter chimney at a speed of 6 ft/s. As shown in Video V5.4 and Fig. P5.22, due to the wind, after a few diameters downstream, the exhaust flows horizontally with the wind at a speed of 15 ft/s. Determine the horizontal component of the force applied by the wind on the exhaust gases.

**Figure P5.22 Explanation**:
- The diagram illustrates a cylindrical chimney with exhaust gases flowing out.
- The chimney has a diameter of 4 feet.
- The exhaust exits the chimney vertically at a speed of 6 ft/s.
- After interacting with wind, the exhaust flows horizontally at 15 ft/s.
- The wind speed is also 15 ft/s in the horizontal direction.
- Arrows depict the velocity of the exhaust and the wind.
The task is to determine the horizontal force component exerted by the wind on the exhaust gases.
