    Scrambled Spreadsheet Images

    I'm in the same boat with Denial. My company installed a coporate update which included Microsoft's recent update. I cannot simply remove the update like Spats. I've followed some of the threads indicated in IDS's link and have been painfully trying to implement some workarounds within VB...

    Addding Data with DIFFERENT Scales

    Thanks IRstuff for your response. I thought about your suggestion before, but it doesn't work out so well. I've monitored supply and return water temps from a chilled water loop as well as the flow. I need to apply the following formula for each data point to calculate tons cooling: Tons =...

    Addding Data with DIFFERENT Scales

    I've got two sets of data that I need to do some basic math with. One is set at 5 min intervals while the other is set at 6 min intervals. Is there some way to do this without manually manipulating one set of data?

    Equivalent Full Load Hours (EFLH)

    I've got a question regarding EFLH and Cooling Degree Days (CDD). I've found an equation to calculating EFLH as follows: EFLH = 24 x CDD / delta T My question is, "Delta T of what?" Thanks in advance.

    Military Time Calculations

    Thanks everyone for your help. I was able to get it after following the directions on the first response. I ended up taking the difference between the sunset and sunrise in the same day to calculate "daytime" and 24 - "daytime" as "night". Gotta love this site.

    Manipulating Weather data again...

    Thanks InspEngr. Shortly after I started the thread, I figured out a method based on responses to an earlier "Manipulating Weather Data" thread I started one year ago. Basically I did a SUMIF divided by a COUNTIF. I would still like to see your spreadsheet to compare to. Send to...

    Boiler Combustion Efficiency

    I'm looking for some Boiler Combustion Efficiency tables. I seem to recall one with %Excess Air, %02 and temperature. Does anyone know where I can find one? I have flue gas analysis data telling me I have 8.3% O2. I believe it should be in the 2-3% range. Oh yeah, the fuel is natural gas...

    Manipulating Weather Data

    Thanks ivymike for pointing me in the right direction. The manual method involves a lot of manual highlighting and the frequency function. I've tried out your method, but am a bit confused. I understand the month and the hour portion of the bin code, but don't understand the temperature...
