combination of variables

Calculate the Reynolds numbers for the flow of water and for air through a 4-mm-diameter tube, if the mean velocity is 3 m s and the temperature is 30° C in both cases (see Example 1.4). Assume the air is at standard atmospheric pressure.

Example 1.4

Viscosity and Dimensionless Quantities

GIVEN A dimensionless combination of variables that is important in the study of viscous flow through pipes is called the Reynolds number, Re, defined as ρVD/μ where, e, as indicated in Fig. E1.4, is the fluid density, V the mean fluid velocity, D the pipe diameter, and μ the find viscosity. A Newtonian fluid having a viscosity of 0.38 N. s/m2 and a specific gravity of 0.91 flows through a 25-mmdiameter pipe with a velocity of 2.6 m/s.

FIND Determine the value of the Reynolds number using 1a2 SI units and 1b2 BG units.
