The pressure drops 4P = P₁ P2 through a long section of round pipe can be written in terms of the shear stress Tw along the wall. Shown in Figure 3 is the shear stress acting by the wall on the fluid. The shaded region is a control volume composed of the fluid in the pipe between axial locations 1 and 2. Using the method of repeating variables, generate a relationship for pressure drop as a function of all other parameters Final ans AP = P μ (₁ AP= {(₂17₂) P₁ CV UPL м = (²1 ²² an! VPL O P.H. L V
2. Show, with sketches, the differences between the shear stress of solids and fluids when subjected to a tangential force. 3. Is there any concern that blood flow in the human retina will become turbulent? If the blood density is 1060 kg/m³, the inside diameter of the arteriole is 0.0075 cm, the mean velocity in the vessel is 3 cm/s, and the viscosity measured as 0.00349 Ns/m².
A certain equiangular strain gauge rosette is made up of three separate gauges. After it has been installed it is found that one of the gauges has, in error, been taken from an odd batch; its gauge factor is 2.0, that of the other two being 2.2. As the three gauges appear identical it is impossible to say which is the rogue and it is decided to proceed with the test. The following strain readings are obtained using a gauge factor setting on the strain gauge equipment of 2.2: Gauge direction 0o 60o 120o Strain * 10-6 +100 -250 +300 Taking into account the various gauge factor values evaluate the greatest possible shear stress value these readings can represent. For the specimen material E = 210 GN/m2 and v = 0.3
