    RO system intake

    Hello All, I work in a plant where we use a reverse osmosis system for water purification instead of our DI loop. The only issue with this is that unlike the DI system, we don't have a direct reading for the total amount of gallons it uses. Is it possible to use an ultrasonic flow meter on the...

    Correlation Coefficient

    *In another sense, if I have a constant value that relates two of the variables, I can predict what one will be within a reasonable margin of error during the next few years (I would be able to forecast the amount of sanitary or cooling water in the next few years give or take a few gallons)...

    Correlation Coefficient

    IRstuff, I understand what you mean and that is how I approached it from the beginning but the main question I would say is how to ensure the repeatability of the number I solve for. That is why I tried the correlation coefficient first between the two sets of data. This showed that they...

    Correlation Coefficient

    Yes thats how I got 0.7 but this is just a sample for for one year, 2011. I want to know that if I can use this same 0.7 moving forward to predict the values as long as our production doesn't vary too much. I'm not sure if there is a more sophisticated way to explain or do this but we want to be...

    Correlation Coefficient

    Hello all, I am working for a plant and we have executed a green initiative that starts with the monitoring of our total usage in water, electricity, fuel etc. We have a table to do this, but it requires way too much data entry and time to complete so we are trying to use excel to automate it...

    Design Engineering questions

    I started looking through it and first thank you so much for the resources Pennpiper. This is still something I want to do. Plumbing design also interests me since I've always liked the way fluids were transferred within systems. I've met someone who works for the process piping industry who...

    Heat transfer Chilled water tank help - Aspiring HVAC/thermal Engineer

    I apologize Latexman I just saw the rule board, won't happen again. @Som1973 Thank you, I apologize I did not list the dimensions. H = 15' D = 8' Tw (temp of water) = 55 F Ta (temp of air) = 80 F with heat transfer calculation what I did was Qwater = α *A * (Tw-Ta) α = 0.58 A= 376.8...
