Thus for example we may answer the question, #How much water will an eight-inch pipe carry as compared with a six-inch, with the same loss of pressure?* Follow down the first column to 8; then to the right under column headed 6, we find 2.0©, which shows us that an eight-inch pipe will carry 2.05 times as much as a slx-inch; or, in other words, an eight-inch pipe is a little better than two six-inch pipes. oooOooo
