Viscosity is defined as the measurement of the resistance of a fluid to gradual deformation by shear or tensile stress. A shear stress will be developed as a fluid moves along the fluid mechanics system. There are severalcommon methods used to measure the viscosity such as viscometers or rheometers. A falling-ball viscometer as shown in Figure 1 is being used to measure the viscosity. A 0.35 cm diameter steel ball with a specific gravity of 7.7 is allowed to fall freely in a heavy fuel oil having specific gravity of 0.90. The ball is observed to fall 50 cm in 2 hours. i) Calculate the dynamic viscosity of the oil in Pa.s.

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.
