Water flow in a pipe can be represented by the Reynolds number Re which is dimensionless.
The Reynolds number is determined by the equation Re= (w Vw Dp ) / ?w where:
w = water density = 1.94 slug/ft3
Vw = water velocity = 156 km/s
Dp = pipe diameter = 8.5 in
?w = water viscosity = 4x10-4 kg/m-s
Part A: Do a dimension check to show that Re is dimensionless (i.e. use M, L, t, etc.)
Part B: Determine the value of Re using the values given above
