I've decided to outsource your argument. Call your local HVAC people. Ask them how big a blower you need to move air through 50 feet of tube. Then ask them how big a blower you need to move it through a 300 ft tube to keep the same volume of air moving. When they tell you it will require a bigger blower, you may begin your argument, and tell them what morons they are. I'm sure they will be just as impressed with you as I am.

I take it all back - science isn't your problem, literacy is. When you feel like actually reading my posts, do drop me a line, and we'll pick up where we left off.
