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 µ = 0.022 p= 1150.0 qms = 7.0 g = 9.81) units : L ~ m; D ~ m; µ ~ Pa · s; p~ Confirm that this is laminar flow and then calculate the resistance. b) Pump Resistance from Pump Curve Consider the following pump curve: [Feet] [Meters] 30어 Find the pump resistance if the pump is supporting 15 meters of discharge head pressure, at a flow rate of 300 L/minute. 8어 25어 7어 100 PSI L/min Determine the pump resistance in Pa 20어 6어 85 PSI 50 SCFM 5어75 PSI Note that standard pump curves are 15어 60 PSI 4어 80 SCFM oriented opposite to the curves in the text.
