PRES

A simple perfect gas monitored volume where the relative pressure is a function of relative volume or a function of time.

In the PRES monitored volume, the relative pressure is defined as Prel = pressure inside of monitored volume - atmospheric pressure.

The relative pressure is defined using a function in one of two ways. By default, the relative pressure is defined as a function of the relative volume P rel ( V 0 V ) MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq=Jc9 vqaqpepm0xbbG8FasPYRqj0=yi0dXdbba9pGe9xq=JbbG8A8frFve9 Fve9Ff0dmeaabaqaciGacaGaaeqabaWaaeaaeaaakeaacaWGqbWaaS baaSqaaiaadkhacaWGLbGaamiBaaqabaGcdaqadiqaamaalaaabaGa amOvamaaBaaaleaacaaIWaaabeaaaOqaaiaadAfaaaaacaGLOaGaay zkaaaaaa@3E7C@ , or the pressure can be a function of time P rel ( t ) MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq=Jc9 vqaqpepm0xbbG8FasPYRqj0=yi0dXdbba9pGe9xq=JbbG8A8frFve9 Fve9Ff0dmeaabaqaciGacaGaaeqabaWaaeaaeaaakeaacaWGqbWaaS baaSqaaiaadkhacaWGLbGaamiBaaqabaGcdaqadiqaaiaadshaaiaa wIcacaGLPaaaaaa@3CBF@ .
