    Need Expert Advice on Calculating Pressure Buildup in Fixed Volume Vessel

    Thank you all. Glad to see the many different ways to skin this cat. If I ever do a dynamic model of this or get to witness it in real life I'll be sure to update... -M

    Need Expert Advice on Calculating Pressure Buildup in Fixed Volume Vessel

    Thank you everyone. @Pierreick, That mathcad solution is intriguing. @Mr George: Option B. @Mr. 44, LI, & LM, Some additional detail... You could assume this is a long pipe fed by a valve controlling 300PSIG on the inlet of that pipe. The pipe feeds a vessel, no inlet control valve. The...

    Need Expert Advice on Calculating Pressure Buildup in Fixed Volume Vessel

    @LittleInch can I not assume there is a "compressor" supplying 90MMSCFD at 300PSIG at the inlet of the system? Regardless if there is an actual compressor there or not? I'm only looking for "rule of thumb" accuracy here and am not going to look into any transient analysis. Just need an...

    Need Expert Advice on Calculating Pressure Buildup in Fixed Volume Vessel

    @1503-44, @Littleinch, and @pierreick I approached this a bit differently...I approached this from the work equation by integrating for change in pressure. w= ∫ VdP = P1*V1*ln( P2/P1 ). Finding the work to fill the volume from 100PSIG to 250PSIG, then finding the work done by compression ...

    Need Expert Advice on Calculating Pressure Buildup in Fixed Volume Vessel

    "Hello community, I'm currently facing a challenging situation and would greatly appreciate some expert advice. Here's the scenario: I have a fixed volume vessel with a total volume of 15458 ft³. The volumetric flow rate through this volume is 90 MMSCFD. The initial temperature of the gas is...
