Suhail P Posted June 17, 2021 Report Share Posted June 17, 2021 Hello Everyone, I am designing an air bearing table with an internal air supply. The system has three flat air bearings each with a maximum flow rate of 1.32 NLPM at 0.41 MPa (60 psi). Instead of an external supply of air from a compressor, I am planning to supply air from a portable storage tank, so that i can make the system free from any external connections. I am facing difficulty to find the tank size and storage pressure. I did the following calculations For a 30-minute run Volume of air required by the bearings V1= 1.32 x 30 x 3 = 118.8 L at 1.01325 bar (P1) Now i can choose the tank volume V2 and can find the pressure P2 = (118.8x1.01325)/V2 Or i can choose the tank pressure P2 and can find the volume V2 = (118.8*1.01325)P2 can someone please verify if the calculation correct or not? I need to limit the tank size to the small canister of size 1L or 2L, so please suggest to me any air storage tank suppliers so that I can find out standard air storage canister sizes.

Andika Dinata Posted June 30, 2021 Report Share Posted June 30, 2021 I just try to help you buddy P1 x V1 = P2 x V2 P1 = 1,01 bar V1 = 118,8 L P*V=k k is constanta. which the value is same like k1=k2 you can chose P1=P2 or V1=V2 subtitute in {P1 x V1 = P1 x V2} or {P1 x V1 = P2 x V1} The rest of all equations can calculate properly.
