AI Thread Summary
To release 400ml of hydraulic oil in 10 seconds from a cylinder with a height of 300mm and a diameter of 80mm, Bernoulli's Principle should be applied, considering head losses due to pipe friction and minor losses. The necessary vertical pressure can be calculated by determining the required head for the desired flow rate through the 12mm diameter exit pipe. Iterative calculations may be needed to refine the pressure requirements. Participants in the discussion emphasize the importance of understanding fluid dynamics for accurate measurements. This approach will help achieve the desired oil release efficiently.

hi good day everyone,

Typically i have a 300mm height, 80mm diameter cylinder filled with 400ml hydraulic oil. It connected to 2m length pipe via 12mm diameter exit. Density of hydraulic oil is assumed to be 900kg/m^3. My task is to release the 400ml hydraulic oil in 10seconds. So in this case how could i figure out and measure the desired vertically pressure pls?! thanks in advanced :confused:kinki_ania@hotmail.com

Use Bernoulli's Principle and account for the head losses (pipe friction and minor losses) and determine the required head needed for the desired flow rate. It may take some iteration.

okok.. thank for guiding me a bright way ahead.. let me try 1st..
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
