An inclined tube manometer has the area of the reservoir as 277 mm^2 and diameter of the inclined tube as 3.64 mm. The tube is inclined at an angle of 10.5°C with the horizontal. The manometer liquid has a specific gravity of 0.327. The inclined tube is open to atmosphere. A gauge pressure equivalent to 10.2 mm of water is applied to the reservoir. Find the deflection distance of the manometer liquid along the tube.

A cylinder has 40 holes evenly spaced around its surface. Each hole has a diameter of 5mm. One end of the cylinder is sealed with an end cap and the other end is connected to a vacuum air pump. 40 spheres, each with a weight of 0.1 grams, have a diameter of 8mm will be placed over each hole in the cylinder. Calculate the minimum suction power (in Pascals) required to produce the pressure in order to hold the spheres to the cylinder.

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.

4. A differential manometer is connected at the two points A and B of two pipes as shown in the figure. The pipe A contains a liquid of S.G. = 1.5 while pipe B contains a liquid of S.G. = 0.9. The pressures at A and B are 98.1 kPa and 176.58 kPa, respectively. Find the difference (h) in mercury level in the differential manometer. Use S.G. = 13.6 for mercury.
