    CFM and PSI Requirements for Abrasive Blasting 80' Steel Pipe

    Yep, like I always say: Good engineers make good guesses.

    CFM and PSI Requirements for Abrasive Blasting 80' Steel Pipe

    I can see why you've never tested different basic assumptions. Guess there's not many manufacturing companies or engineering firms located at sea-level ... well ... less you are from Louisiana maybe. Could be the reason for no 'written-in-stone' basic assumptions is because they would, I...

    CFM and PSI Requirements for Abrasive Blasting 80' Steel Pipe

    Agree ... obviously you have to use the same calculation the vendor uses but I was wondering if there is a standard written in stone anywhere that is appropriate for designing blowers and such. I have a lot of military standards from when I was designing Apache's but not one for that and I don't...

    CFM and PSI Requirements for Abrasive Blasting 80' Steel Pipe

    Thing is I've never been able to find a definition of SCFM that everyone agrees with. Some claim, as I remember, the air should be like 68° F, 36% Relative Humidity measured at sea level (Ah! a trip to the ocean). Others say the RH should be zero and still others 50%, on and on. Hmm, makes me...

    Force calculation for lock-rotor motor

    Thank you Sir! I'll see if I can't puzzle that out. I always say: Well ... it seems we don't have time to do it right, we only have time to do it over. ~Larry

    Force calculation for lock-rotor motor

    I have 1700 HP induction motors that I need to do lock-rotor test on. Force applied to the bolts on the lock-rotor flange should be mass X acceleration I guess but what I'm stuck on is what would the acceleration be of a motor that's not turning ... is that a dumb question or what! Eventhough...
