Number of Pneumatic Air Tanks

[Dr.Gusta]

My team does not have much experience with pneumatics and this year we are planning to have pneumatics play a major part in our robots function. We are planning on using four 5/16" bore and 14" stroke single action (spring return) that will open and close up to 25 time but let's say 50 times to be safe. Also there will be another smaller cyllender of unknown bore but about 5" stroke dual action and would probably only open and close 5 times. We would also have the standard Viair compressor. We were thinking 6 of these tanks (http://www.andymark.com/product-p/am-2649.htm) pressurized at 120psi. Do you think that will be sufficient?
