(Just Question a.) A water filled pipe has water flowing at v1= 5.90 m/s in a section of pipe where the diameter is d1= 20.2 cm and the pressure is known to be P1= 7.00×104 N/m2 above atmospheric pressure.     If the pipe carries the water 3.5 meters up hill without any change in diameter, what is the new absolute pressure within the pipe? After flowing up the hill described above, the pipe narrows to 80% of its original radius, what will be the new water velocity (v2) in the pipe? What will be the absolute pressure (P3) in the smaller pipe?   a. What is the volume flow rate through the smaller pipe?

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.

A 10000 litre water tank is placed on a building roof and filled to capacity.  The empty tank has a mass of 550kg.  It is supported on 4 feet, each of which is a 300 x 300 mm steel plate.  What is the pressure exerted by each plate, in Pa?  (Round your answer to 2 significant figures)

Find the force of oil on the top surface CD of the figure below if the liquid level in the open pipe is reduced by 4.0 ft.

Consider the pressure and force acting on the pool retaining a reservoir of water. Suppose the pool is 50m wide and the water is 8m deep, as illustrated below.   (a) What is the Gauge pressure on the dam due to the water?   (b) What is the absolute pressure at10m depth of the dam?   (C) Calculate the force exerted against the dam. Density of water is 1000kg/m3.

The device shown is the buoyancy measurement device used to measure the liquid height change. A pressure sensor is installed at the bottom of the tank, and a force sensor is installed to measure the upward force on the horizontal lever. The distances to the pivot point from the force sensor and cylinder are X1 and X2, respectively.  The reference pressure at the reference liquid height, h0, to the bottom of the cylinder is pref. (4) If the force measured by the force sensor is Fsensor = 7.53 N, X1 = 1.58 m, X2 = 0.17 m, the diameter of the cylinder is D = 0.05 m,  and the specific weight of the liquid is γf = 8.70 kN/m3, calculate the liquid height difference, Δh, relative to the reference height h0. __________ m.
