1. Fluid flows at a rate of 2.0 L/s through a pipe with a diameter of 10 cm. The pipe then goes up a height of 5m while narrowing to a diameter of 5 cm. What is the pressure gradient (the change in pressure) from the top to the bottom of the pipe? [hint: draw this and label with P1, v1, P2, v2 etc.)
2. A hurricane wind blows across the top of a flat roof measuring 12 m by 5m at a speed of 120 km/h.
1) Is the air pressure above the roof higher or lower than the pressure inside the house? Describe.
2) Discover the pressure difference.
3) How much force is exerted on the roof? If the roof's structure fails, will in “blow in” or “blow out”?
