3. Air flows steadily through a pipe of circular cross-section shown below. At point 2, a tube connected to thepipe extends downward into a tub of water at rest. Air leaves the pipe at point 3 to the atmosphere. For thepipe, the cross-sectional areas A₁ = A3 > A2. Derive an expression for the height h to which water will risein the vertical tube, as a function of the specific gravity of air (SG Pair Pwater), velocity at point 1 (V₁),pipe diameters at point 1 (D₁) and point 2 (D2), and any relevant constants. You may assume that air isincompressible and inviscid (thus, flow variables are all uniform at any cross-section).=Air in123Air out

In the system in the attached image, a pressure change of 35 kPa in pressure of air occurs. Here the brine-mercury interface in the right vertical tube drops by 6 mm in the brine level, while the pressue in the brine pipe remains constant. What is the ratio of A2/A1?
As shown in figure, water flows through pipe A and B. The pressure difference of these two points is to be measured by multiple tube manometers. Oil with specific gravity 0.82 in the upper portion of inverted U tube and mercury in the bottom of both ends. Determine the pressure diffference.
Which is the most accurate statement of Bernoulli's Principle? Select one: O a. Fast -moving air causes lower pressure O b. Lower pressure causes fast-moving air O c. Both A and B O d. None of these The body is stable if the center of gravity of the body is below the metacenter. Answer: The amount of energy per pound or Newton of fluid is called the head. Answer: For incompressible fluids, the flow rate is constant (write in small letters).

In flat areas, water towers are used to supply water to houses. Water is pumped into the tower, and then directed from the tower to houses so that when people turn the water on there is water pressure. The top of the tower is vented to the atmosphere. (a) What is the gauge pressure (total pressure minus atmospheric pressure) at each of the two houses? (in Bernoulli's equation, if the water is not running, you can set v = 0 on both sides, and the external pressure in the water tower is just atmospheric pressure). (b) If a faucet is circular with diameter of 2.0 cm, what is the velocity of the water in each house? You can assume that the velocity of water within the tower is negligible.
