In the steady flow of a Newtonian fluid through a long uniform
circular tube, if NRe <2100 the flow is laminar and
the fluid elements move in smooth, straight, parallel lines. Under
these conditions, it is known that the relation between the flow
rate and the pressure drop in the pipe does not depend upon the
fluid density or the pipe wall material.
- Perform a dimensional analysis of this system to determine the
dimensionless groups that apply. Express your result in a form in
which the Reynolds number can be identified. (5 p/100
p)
- If water is flowing at a rate of 0.5 gpm through a pipe with an
inner diameter of 1 in., what is the value of the Reynolds number?
If the diameter is doubled at the same flow rate, what will be the
effect on the Reynolds number and on the pressure drop? (5
p/100 p)
