When greater precision is required for pressure measurements, a device called micromanometer is used as shown in the figure. Suppose that an initial static equilibrium, the micromanometer has x = 1.22 m and y = 1.36 m. If the pressure at pt. A is increased by 5 KPa, to what height will the fluid in the 1 cm. diameter tube rise? I cm.o X-1.22 m 0.1 cm, y= 1:36m. sp.gr.=0.g

In the benzene plant, the pressure drop at some point of a pipeline in which benzene is passing through is measured with a U-tube manometer (Rm,1) as 10 cm (1stsituation). The manometer fluid is carbon tetrachloride(CCl4). Then, in order to avoid CCl4 poisoning, it is decided to add a layer of water to both arms of manometer (2nd situation). So, 4 cm of water is added to the left arm and 8 cm of water is added to right arm. In this newsituation, what will be the height difference of manometer fluid (CCl4) between the arms of the manometer (Rm,2)?Data: ρbenzene=876 kg/m3, ρwater=997 kg/m3, ρCCl4=1587 kg/m3

A catheter-sensor system for invasive pressure measurements has a catheter with a length of 1 m and a diameter of 2.5 mm. The catheter is filled with water at 20 C, with viscosity  = 0.001 Pa.s and density  = 103 kg/m3. The diaphragm elasticity Ed equals 0.5x1015 N/m5. a. Draw the simplified electrical model of the pressure measurement set-up that includes the catheter and the diaphragm and determine the transfer function of the pressure measurement system. b. Compute the natural frequency and damping ratio of this system. c. The current system has a damping ratio that is far from optimal. Suppose you are pinching the catheter for a small length lx so that the catheter diameter reduces to 0.2mm. Assuming the pinch to affect the resistance only, determine the length lx such that an optimal damping ratio  = 0.7 is obtained. d. Suppose that the assumption of purely resistive effects of the pinch cannot be made. Discuss (without calculations) the consequences on the derivation of lx.
