Verify that the Reynolds number is dimensionless using the SI. Reynolds number, VD/: Regarding the FLT system, the dimensions of the density, velocity, diameter and viscosity are depicted as FL-4T2, LT-1, L, and FL-2T respectively. Substituting these underlying dimensions into the corresponding definition of the Reynolds number.

Regarding the MLT system, the dimensions of the density, velocity, diameter, and viscosity are depicted as -3, LT-1, L, and ML-1T-1 respectively. Substituting these underlying dimensions into the corresponding definition of the Reynolds numb er.

Therefore, the Reynolds number is normally dimensionless regardless of the unit system utilized.

The number of cars that pass through an intersection of two busy streets during the evening committee on a typical work day - The average number will be 12,500 automobiles assuming that all cars will be passing through the intersection ones.

The number of bricks that form the exterior of a large building on a university campus - Assume that the size of the exterior of the large building is a square size measuring size 100 x 100 ft and the height is also taken as 100 ft. Also, take the size of every brick to be 1ft x 6 inches. Therefore the number of bricks will be = (100*100*100)/ (1*6) = 166,666.67 = 166,167 bricks.

The volume of concrete in the sidewalks on a university campus - Assume that the size of the exterior of the large building is a square size measuring size 100 x 100 ft and the height is also taken as 100 ft. Also, assume that the sidewalks on a university campus are 300 miles. This volume of the concrete will be = (100*100*100)*300 = 300,000,000ft3
