Data Analysis Using pressure

Temperature of the air in the rig can be calculated

Page 15: Safety Relief Valve Test Rig Update

Data Analysis Using pressure

Mass of the air in the rig can be calculated

Time rate change of rig’s air mass allows mass flow to be estimated

Future Plans

We are continuing to shake test the rig

Possible compressed air line in future

We are considering what additional testing we can perform
