Chapter 12, Problem 18PE
Suppose you have a wind speed gauge like the pitot tube shown in Example 12.2(b). By what factor must wind speed increase to double the value of h in the manometer? Is this independent of the moving fluid and the fluid in the manometer?

An airplane is in level flight at low altitude, so that atmospheric pressure and densities are 1 atm and 1kg/m3 , respectively. There is a pitot tube attached to the airplane, so that air entering the tube stagnates at the rear of the tube. The stagnation pressure is measured to be 1.45x105 Pa. What is the speed of the airplane? (The laser is there to detect particulates in the air which might interfere with the operation of the probe).
note: Please solve and explain most steps. Thank you!! :)

We’ve seen that fish can control their buoyancy through the use of a swim bladder, a gas-filled organ inside the body. You can assume that the gas pressure inside the swim bladder is roughly equal to the external water pressure. A fish swimming at a particular depth adjusts the volume of its swim bladder to give it neutral buoyancy. If the fish swims upward or downward, the changing water pressure causes the bladder to expand or contract. Consequently, the fish must adjust the quantity of gas to restore the original volume and thus reestablish neutral buoyancy. Consider a large, 7.0 kg striped bass with a volume of 7.0 L. When neutrally buoyant, 7.0% of the fish’s volume is taken up by the swim bladder. Assume a bodytemperature of 15°C.a. How many moles of air are in the swim bladder when the fish is at a depth of 80 ft?b. What will the volume of the swim bladder be if the fish ascends to a 50 ft depth without changing the quantity of gas?c. To return the swim bladder to its original…
