Hi

I have to calculate a line under Pressure: P = 0.6 Bar
I want to know if I have to enter this value as it's in P2 = 0.6 Bar or I have to calculate first the outside pressure P2 = 1-0.6 = 0.4 Bar and entering P2 = 0.4 Bar
I'm asking this question cause in the operating conditions it's writing P = 0.6 Bar and I don't Know if it's inside pressure or whene we talk about vaccum the given pressure is automaticlly the outside pressure?
