3 cards from this section. Quick, good the night before a test.
Define Reynolds Number.
Think about how fluid types relate to flow behavior.
What is Laminar Flow?
Consider how the fluid looks when moving slowly.
What does a Reynolds number below 2000 indicate?
Reflect on the flow behavior associated with smooth surfaces.
True or False: A globe valve generally results in less energy loss than a gate valve.
Think about how each valve controls and restricts the flow.
Calculate the Wayne Pipe Reynolds number for a flow of 5 m/s through a pipe of diameter 0.1 m with a viscosity of 0.002 Pa.s. Discuss whether the flow is laminar or turbulent.
Remember to use the formula for Reynolds number and interpret the result.
Design a small water system using a gate valve and globe valve. Address the potential efficiency issues with energy losses. What modifications would you recommend?
Consider the operational context of each valve and where it may affect flow.
