Figure 13-37 shows a Pitot-static tube, a device used for measuring the speed of a gas. The inner pipe faces the incoming fluid, while the ring of holes in the outer tube is parallel to the gas flow. Show that the speed of the gas is given by where is the density of the liquid used in the manometer and is the density of the gas.

Second, sounds can be considered as being original or reproduced. 3. Another fundamental difference is between transient and steady sound. a.
