3. Homework
Water flows through a 2-inch diameter pipe at 200 lbm/min. Its temperature is 60oF. Find the velocity of water flow (fps).

4. Homework
Water from a pipe line is diverted into weigh tank for exactly 9 minutes. Tank weight increases 4765 lbf. Water temperature is 60oF. Find the flow rate (gpm).

5. Homework
Steady flow of gas through a pipe whose diameter decreases from 1.0 meter to 60cm. The gas density decreases from 2 kg/m3 to 1.6 kg/m3. The entering velocity is 25 m/s. What is exit velocity (m/s)?

6. Example 60 cm diameter How long will it take for level to drop from
h = 3m to
h = 30cm?
3 cm diameter
