Question
![Determine the resistance in each scenario presented. Explain whether the resistance is linear or not,
and if not describe the relation, finally, explain how it can be linearized about a specific condition.
Be sure to state the units and demonstrate that they are correct using the appropriate pressure/flow
relation.
a) Laminar flow
An aqueous solution of 50% glycerol / 50% water is flowing through a pipe with the following system
parameters:
System_Parameters = (L = 100.0 D= 0.2 u= 0.022 p= 1150.0 9m=7.0 g = 9.81)
units : L ~ m; D~ m; µ ~ Pa · s; p~
kg: 4. ~ 8:
Confirm that this is laminar flow and then calculate the resistance.
b) Pump Resistance from Pump Curve
Consider the following pump curve:
