    Aquamine PVC Pipe - Thrust Block?

    For those not familiar with it, aquamine pipe is a pvc piping system that is similiar to victualic for iron pipe. It has couplings that use o-rings and plastic splines that run between a groove in the pipe and a groove in the coupling, essentially locking it together. However, many of the...

    Flow Rate in Parallel Packed Bed Reactors

    Ok, Two pipes in parallel, with the total flow rate known, and the pressure drop across each pipe known, what is the flow distribution between the two pipes? With gas systems, does the resistance analogy hold? What about with liquid systems? Thanks,

    Flow Rate in Parallel Packed Bed Reactors

    What is the best way to determine the flow rate in parallel packed bed reactors knowing the total flow rate and pressure drop across each bed? Is a simple resistance model a good approach, treating the pressure drop as a resistance in a parallel circuit.Suming the individual flow rates from this...

    Parallel Pumping Info or Data

    OK, following CB's analogy, where does Resistance fit in? Is there an associaiton between head loss and resistance? The reason why i ask is this: If you had two packed bed reactors in parallel, and you knew the total flow rate to the system, how would you determine the flow rate to each, if you...

    Viscosity of domestic sewage?

    Most likely you won't be moving sewage sludge at high Reynold's numbers, so your viscosity, and thus your kinematic viscosity become very important when calculating head loss. Generally you need to oversize the pipe. Unless your Total Solids is below 1-2%, I wouldn't use the same viscosity as...
