Does a Pressure Regulator Maintain Equal Flow Rates at Inlet and Outlet?

AI Thread Summary
Flow rate at the inlet of a pressure regulator is equal to the flow rate at the outlet, as mass is conserved in a closed system. This principle holds true as long as there are no leaks on the high-pressure side. The pressure regulator reduces the pressure while maintaining the same mass flow rate. Therefore, all fluid entering the regulator from the high-pressure tank exits at a lower pressure. Understanding this concept is crucial for effective fluid system design.

Is flow rate at inlet of pressure regulator ( not relief valve) equal to flow rate at outlet ?

Mass is conserved, so the mass flow rate is the same at the inlet and outlet -- asssuming that there are no leaks on the high pressure side of things. Everything coming out of the high pressure tank shuld be going out at lower pressure on the outlet.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
