This document contains 23 figures from the 10th edition of the textbook "Applied Physics" by Dale Ewen, Neill Schurter, and P. Erik Gundersen. The figures illustrate various principles of fluid mechanics, including how pressure increases with depth in liquids, how pressure is transmitted uniformly in all directions in confined liquids, and examples of streamline and turbulent fluid flow.

Figure 13.1 (a) The pressure on a submerged object is exerted by the liquid in all directions. The pressure at ocean-
floor level is so great that very strong containers must be built to withstand the enormous pressures.

Figure 13.1 (continued) (b) When a force is exerted on a liquid in a container, the force is exerted uniformly in all
directions. Note that the liquid squirts out of the holes uniformly in all directions.

depth.

Figure 13.17 Streamline flow of a fluid through a smooth tube or pipe is shown in (a) and (b). Water flowing in a creek
or a mountain stream over and around rocks, resulting in sudden changes in direction and speed, is a common
example of turbulent flow as in (c).

Figure 13.19 A Venturi meter shows that the higher the speed of a fluid through a tube, the lower the pressure; the
lower the speed of a fluid, the higher the pressure.
