Question
Oil flows laminarly through a pipe of 25 millimeters in diameter and 100 millimeters in length.
The density of the oil flowing through this pipe changes to 850 kg/m^3 and its flow rate to Q(t)=0,001sin wt.
Accordingly, what will be the amplitude (PR) of the pressure drop caused by the fluid resistance and the amplitude (PL) of the pressure drop caused by the inertance?
Which W limits should be PR/PL>=0.05
In what frequency regions does the pipe behave close to a pure resistance or close to a pure inertance?
(if necessary,
The absolute viscosity of the oil is u = 30 cp.)
