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...

Calculate the Reynolds number, Re- (2rpv)/ n, for the following situations and decide whether the flow of fluid around them is laminar or turbulent. Then calculate the frag force using the appropriate formula. For the radius, use r 2(Area/perimeter) which, for a circle, gives the radius. Densities and viscosities are in the table on page 2. Also, to keep things uniform, we will use the boundaries for laminar and turbulent flow from Engineer's Toolbox, also on pg. 2 [1] A...
