    Residence Time Distributions

    Hi, Got a quick question I was hoping that someone might be able to help me with? I'm analysing some aging data for a R&D plug flow reactor; Its a residence time data set, based on the pulse injection method. we're happy with the analysis of the outlet curve but due to the nature of the beast...

    The Marcet Boiler

    Hi, Odd question but hoping you can shed some light on it (and hoping I've posted it in roughly the right forum); In a lot of engineering departments at universities, a "marcet boiler" is used to investigate the relationship between the pressure and temperature of saturated steam, in...

    Liquid Ring Vacuum pump

    Hi! I’ve got an odd question and I’m not sure there is a definitive correct answer but I’d appreciate your postulations! A customer uses a Liquid ring vacuum pump to create a vacuum in a vessel we supply. Whilst carrying out a service on the vessel recently we were asked to inspect the pump...

    Overall heat trasnfer coefficient

    We've got an odd design of heat exchanger reactor (Its sort of multi pass cross flow as a best description in Heat exchanger terms.) When we calculate values for U we get different values for whenever we run the heat exchanger at different stream 1 flowrate, stream 2 flowrates, stream 1 inlet...

    Heat transfer area

    Hi! We've been 'messing' around with a new micro reactor type device. We're now wanting to estimate the heat transfer coefficients for the device. It basically a straight etched channel in a sheet of 316L SS. The heat transfer occurs throgh the base of the channel to a utility stream passing...
