True or False: As temperature increases, pressure drop increases.

The correct assertion is that as temperature increases, pressure drop does not necessarily increase, which supports the selection of the answer indicating false. In fluid dynamics, temperature affects the viscosity of a fluid. When the temperature of a fluid rises, its viscosity typically decreases, which can lead to a reduction in resistance to flow. This means that for a given flow rate, higher temperatures could actually result in a lower pressure drop across a particular section of tubing or a device.

Understanding this principle is important in various applications, including cardiovascular perfusion, where controlled temperatures are crucial during procedures. The relationship between temperature and pressure drop is interconnected with the physical properties of fluids, making considerations of context essential. In some systems, depending on specific conditions like the type of fluid being used or the system configuration, one might find variations in behavior, but the fundamental principle remains that increased temperature generally correlates with lower viscosity and potentially lower pressure drop in many scenarios.
