PROB E. A capillary –tube viscometer is being selected to measure viscosity of a liquid food. The maximum viscosity to be measured will be 230 cP and the maximum mass rate is 900 grams per hour. If the tube length is 10 cm and the maximum sustainable pressure is 25 Pa, determine the nominal diameter size of the tube to be used.
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

When a clean glass tube with a diameter of 2 mm is immersed in water at 20 ° C, how many mm will the capillary rise occur in the glass tube? For water at 20 ° C, surface tension is given as 0.073 N / m, density 1000 kg / m3, contact angle 0 ° C and gravitational acceleration 10 m / s2.
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.
