A model test is to be conducted in a water tunnel using a 1: 20 model of a submarine, which is to travel at a speed of 12 km/h deep under sea surface. The water temperature...
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...
Recall that the Reynolds number is a dimensionless number that we use to discuss the flow charecteristics of moving fluids. Generally speaking it is the ratio of momentum forces to viscous forces, and it depends on the diameter of the pipe, the density of the fluid, the velocity of the moving fluid, and the viscosity of the moving fluid. It is normally given by Re Where Re - Reynolds number [dimensionless) p- fuid density v- fud velocity D- pipe diameter...

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.
