Another little known fact about compressed air from an end users point of view is that discharge pressure has a direct impact on flow.In fact,we know from Boyles Law that P1 x V1 = P2 x V2.Where P1 is the initial pressure,V1 is the initial volume,P2 is the final pressure,and V2 is the final volume.Stresses in PressureVessels - Elsevierradial stress is a direct stress,which is a result of the pressure acting directly on the wall,and causes a compressive stress equal to the pressure.In thin-walled vessels this stress is so small compared to the other principal stresses that it is generally ignored.Thus we assume for purposes of analysisStress and high blood pressure What's the connection Could all those short-term stress-related blood pressure spikes add up and cause high blood pressure in the long term? Researchers aren't sure.However,exercising three to five times a week for 30 minutes can reduce your stress level.
