Motion of 



Water io 



Pipe* and 



Canals. 



TABLE I. 



Computed by Mr Smealon, for theiring the Friction of Water in Horizontal Pipes. The Bore of the Pipe leing 

 given, and the f'clocity of the Water therein, the Height of Head, or Column necessary to overcome the Friction 

 and produce that Velocity, is then* by this Table for 100 Feet in length. 



K. B. Find the velocity of the water per second in feet and inches in the first column, or in inches in the 

 cond ; and underneath the diameter of the bore in inches, (disposed in the uppermost row,) you will find the 

 perpendicular height of a column of water in feet and inches, and 10th necessary to overcome the friction of that 

 pipe of 100 feet in length, to obtain the given velocity.
