Students Working in Fluid Dynamics Laboratory, San Francisco State College (Updated last month)

You can view this bundle in the SFSU Over the Years collection area.

Two individuals operate and observe experimental equipment in a fluid dynamics laboratory at San Francisco State College. One adjusts a valve or component on a test setup while the other records data, capturing a moment of applied instruction and analysis in mechanical engineering or applied physics.
