Calculating Air Tank size

[Jonathan Cooke]

Hi everyone
was wondering if you could help me with calculation for a small project of mine. I was trying to use some of the calculators but I'm struggling to figure out the maths involved, its a bit out of my depth.

I need to find the size of tank I would need to provide :
-150 psi for 10 reciprocations to two actuators (25mm bore and 100mm stroke)
-The flow rate does not have to be fast ( if the actuators took around one second to extend that would be optimal.)
-paintball tanks I was looking at can store air up to 3000psi just need to know the size
-I am using PU piping 5mm(ID) around 1 metre in length in total to connect a regulator, solenoid valve, manual cut off valve and a junction to the system.

If anyone could help me out it would be greatly appreciated, I'm doing my final exams in Ireland in school and don't understand most of the concepts Thanks.

You are probably aware that this engineering site does not allow responses to school work. Go to a paint ball shop and get some ideas about the sizes of air tanks on the market.

or try on line suppliers.

JC,

I'll throw you a lifeline here.

For compressible fluids you need to either track mass of the fluid (air in your case) or revert all volumes to a standard volume, usually 1 bara at around 15C.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
