Hi all! I am trying to find specs for Volvo Penta Generators, in particular about the type of lubricants, and the applicable standards. Would you have any idea where i could find documents for that? (I do not own the kit) Thanks!

Hello I would like to know if anyone could point me to some references about atomisation. The system I am look at is a water atomiser/spray, which goal is to atomise the liquid, enhancing the interfacial area between it and the surrounding atmosphere. I would like to be able to estimate the...

Dear all I am looking for information about Construction (Civil Works) standards of Middle East countries. Qatar, for instance, has the Qatar Construction Specifications 2010 (QCS2010). Do you know if other countries have their standards? Any ideas? Many thanks

Dear colleagues I would like to ask if you know about software for simulation of combustion and gasification of biomass and coal, particularly in reactors as fluidised bed, spouted bed, etc. It is known that this kind of simulation can be done using general-purpose CFD software (Fluent...

Hello colleagues I am working with a liquid-solid system (similar to a fluidised bed) and I would like to know if the Geldart particle classification can be used for such systems. Any idea about it? Also, if you have any reference book that deals specifically with solid-liquid and presents...

Thanks - I've found the material you told me about in Perry's! Cheers!

Hello there. I am currently studying spouted beds for biomass treatment, but I am having a hard time understanding some basic concepts. Could you tell me if is there any introductory level book or reference to the subject? Cheers!

Hello there again. Do you know an alternative to Osiadacz's book? I´m having a hard time find a copy of it. Thanks in advance.

Hi BigInch. I appreciate your help. I´m going follow your advice and study Osiadacz in order to get a clear understanding of the basics. But I´d like to ask you for further help: you said that is apparent that my understanding on the subject is not enough. Can you tell me if is there...

Hi Latexman Thanks for your kind help, but the focus of my doubt is not the pressure loss in the valve itself, but how the kirchoff equations will change with the valve addition. Let´s assume that I know how to compute the pressure loss of a valve through Darcy-Weisbach. Adding a valve to the...

Hi there I´m modelling a air flow pipeline using Kirchoff laws and solving it through Newton method. The trouble is when trying to add a valve in this system. I´m programming myself this and cannot use any other software (besides the numerical recipes). The system is composed of 4 fans and 4...

Hi there. I don´t really know much about instrumentation on secondary refining so I need some help. What kind of pressure sensor is used to measure it at the Vaccuum degasser facilities? I know pirani, but it´s very sensible to temperature, so it is probably not. We are thinking about...
