I feel like this should be easy but I'm having a good amount of trouble figuring it out. I'm given the inlet pressure, the length and the inner diameter of the hose and I'm asked to find out the flow rate coming out. I'm also assuming the outlet pressure is atmospheric. Without being given a...
I'm looking into designing a swivel joint for cryogenic applications (33 K >). I'm assuming I'll use 316 SS for the body, PCTFE or something similar for the seals, and a low temp grease. Does anyone have any recommendation on what materials work best? Are there any special requirements for...
I assumed this was easy but I'm having difficulty finding the right equation. I need to calculate the flow rate in GPM of a smooth bore hose. The diameter is 3/8", length is 100 ft, inlet pressure is 250 psi and outlet is atmospheric (14.7 psi). The rest is unknown
We are using a 100 ton Ram to break steel cables. How would you calculate the tensile strength of the Cable using only the gauge pressure? I'm also having a problem because it seems that the pressure required to simply move the Ram is adding to the pressure required to break the cable. Does that...
We are using a punch press and there have been complaints about the comfort for the operator. The operator sits at a chair and actuates the machine with a foot pedal. The problem is there are two solid steel plates attached to the machine that limits the operators leg space. Its uncomfortable...
Can someone explain the difference in flow rates and pressure differences between convoluted and smooth bore hoses? Smooth bore is pretty straight forward but I'm having trouble finding information about convoluted hoses. I assume there would be a pressure drop and a non uniform flow but I can't...
