Hi,
Im looking into water hammer at the moment. I am trying to figure out whether or not my lines are at risk from water hammer stresses.
I have found a design guide which tells me that if t>3L/Vsound then water hammer is not a problem.
t = valve closing time
L = length of column of fluid...
Hi,
I was recently doing some work where I wound up looking at gas densities at different pressures. It got me thinking about values for the universal gas constant, R. At this stage I have seen many different values and units, from 287.05 J/kgK (for air) to 0.08205746 L.atm/K.mol.
My question...
Hi all,
I recently posted a question about nitrogen purging calculations in this forum. Im glad to say that I have resolved my earlier question, but I now have something of a follow up!!
On our plant, we are planning on generating nitrogen at 6-8BarG, distributing it at 3BarG and supplying it...
Hi all,
I have a question regarding the prediction of a boiling point of an oil at varying pressures.
I have a natural/essential oil whose thermodynamic properties I know at 1atm. The properties I have are density, viscosity, specific heat capacity, latent heat of vapourisation and its vapour...
Hi,
Im working on trying to figure out how much N2 is required to inert a vessel such that the final O2 conc. within the vessel is <= 2%.
I have done some sums which indicate that ideally 3.5 tank volumes would be required to do this. The other engineers in my office generally agree that this...
Hi,
I am a recently graduated chemical engineer. Im thinking about returning to university to study for a PhD. One of the projects that I have been offered is in cytomics. Can anyone tell me some more about this area, and its potential scope of use.
I would like to know if I am getting into a...
