When small aerosol particles or microorganism move through air or water, the Reynolds number is very small (Re << 1). Such flows are called creeping flows. The aerodynamic drag force, Fp, on an object in creeping flow is a function only of its speed V, some characteristic length scale L of the object, and fluid viscosity u (see Fig. 4). Use the method of repeating variables to generate a relationship for Fp as a function of the independent variables. Draw...

Problem #3 At very low Reynolds numbers a ball viscometer can be used to measure fluid viscosity by dropping a spherical ball in the fluid and measuring its terminal velocity. Consider a solid ball of radius a = 1cm and density Ps = 2,500 kg/m falling in liquid glycerin with density P = 1,250 kg/m3. The measured terminal velocity of the ball is U = 0.15 m/s. Calculate the viscosity of the liquid.

Question 1 Drag tests show that the drag of a circular disc placed normally to the free-stream velocity (see Figure 1) is a function of the fluid velocity, Vo, the fluid density, p, the fluid viscosity, ?, the disc diameter, D, the free-stream turbulence root mean square velocity, ums, and the turbulence length scale Lx. Here urms and L. are in m/s and m, respectively. By using the Step-by-step method dimensional analysis, develop the r- groups that could be used...
