AI Thread Summary
To prevent leakage when connecting two pipes of varying diameters in a refrigerant system, a proper sealing mechanism such as a compression fitting or a flange should be used. Testing an evaporator's capacity requires a complete air conditioning cycle, including the condenser, compressor, and expansion device, rather than just a refrigerant tank and pump. To ensure no refrigerant remains in the evaporator after testing, a design that facilitates complete drainage back to the tank is necessary, though some gas loss may be inevitable. Minimizing refrigerant left in the heat exchanger can be achieved through careful design and operational practices. Proper system design is crucial for efficiency and to maintain refrigerant integrity.

situation:

1. i have 2 pipes. the source is pipe A and i will connect it to pipe B. the diameter of Pipe varies and has a range, let's say around 1 in. pipe A can be larger than pipe B. what mechanism shall i i use in order to avoid leakage during the process? the fluid is a refrigirant and pressurized like in most air conditioners (window-type)

2. i have this evaporator and i want to test its capacity. do i need to have the complete aircon parts (condenser, compressor, expansion device, etc) or just a refrigirant tank, pump and an air source.?

3. if the test is done, what design shall i use to be sure that there is no refrigirant left in the evaporator and it goes back to the tank?

1. Your first question is unfinished...

2. You can't test an evaporator without a functional air conditioning cycle.

3. Not sure about this one - I guess I always thought a little bit of the gas was lost.
 
so, what will i do to minimize the refrigirant left in the heat exchanger?

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?'
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...
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...
