Problem 42E

What happens to the pressure in water as it speeds up when it is ejected by the nozzle of a garden hose?

Step-by-Step Solution:
Step 1 of 3

ANSWER: The pressure increases as the water comes out of the pipe. This phenomenon can be understood by the divergence law. Let’s imagine the water flow in the pipe is a vector field and the opening of the pipe is the area from which the water flux will come out. The closed surface integral of the vector field and the area of the opening of the pipe gives the flux. As the surface of the opening area of the pipe decreases, the pressure of water increases.
