CHAPTER III 



FLOW OF WATER IN CHANNELS 

 AND PIPES 



THE matter contained in this chapter is common to 

 all books on hydraulics and waterworks, and most 

 books on civil engineering. There is much current 

 literature on the subject. In order however to under- 

 stand what is to follow, and also to make certain 

 calculations necessary in carrying out to a successful 

 issue small water supplies, the engineer must be able 

 to measure the flow of water in channels and to 

 estimate the delivery through pipes in an accurate 

 manner. Hence in the following pages will be dis- 

 cussed briefly, and put as far as it will concern the 

 practical man, the question of steam gauging, and 

 flow in and pressure and friction in pipes, and it is 

 hoped that these remarks will serve as an apology 

 for going over ground which has been covered by 

 many writers before, bearing in mind however that 

 many of the textbooks referred to deal with the 

 matter in a very exhaustive and theoretical way, so 

 much so in fact that the practical man has little time 

 or inclination to wade through them. 



A small river passing through an estate on which 

 water is wanted may serve a variety of purposes, the 

 most commonly occurring being '
