The reaction turbine is best adapted to low heads, with a large supply of water. It is not advisable, under ordinary circumstances, to use it under heads exceeding 100 feet, as its speed is then excessive. It may be used under falls as low as two feet. Five thousand cubic feet of water a minute would give approximately 14 [...](image) (image)

In recent years more efficient forms of the old-fashioned overshoot, pitch-back breast, and undershoot wheels have been developed, by substituting steel or other metal for wood, and altering the shape of the buckets to make better use of the power of falling water. In some forms of overshoot wheels, an efficiency of over 90 per cent is claimed by manufacturers; [...](image) (image)

The Pipe Line For an Impulse Wheelsupermaxshuttlewater wheelWorking Water Powered Mill

The principal items of cost in installing an impulse wheel are in connection with the pipe line, and the governor. In small heads, that is, under 100 feet, the expense of pipe line is low. Frequently, however, the governor will cost more than the water motor itself, although cheaper, yet efficient, makes are now being put on the market to [...](image) (image)

The Impulse, or Tangential Water WheelsupermaxshuttleWorking Water Powered Mill

The modern impulse, or tangential wheel (so called because the driving stream of water strikes the wheel at a tangent) is best adapted to situations where the amount of water is limited, and the head is large. Thus, a mountain brook supplying only seven cubic feet of water a minute–a stream less than two-and-a-half inches deep flowing over a weir [...](image) (image)

The Water Wheel and How To Install Itsupermaxshuttle2410326835_833220afc7_m1

In general, there are two types of water wheels, the _impulse_ wheel and the _reaction_ wheel. Both are called turbines, although the name belongs, more properly, to the reaction wheel alone. Impulse wheels derive their power from the _momentum_ of falling water. Reaction wheels derive their power from the _momentum and pressure_ of falling water. The old-fashioned _undershot_, _overshot_, and _breast_ [...](image) (image)

Let us take still another problem which the prospector may be called on to solve: _A man finds that he can conveniently get a fall of 27 feet. He desires 20 actual horsepower. What quantity of water will be necessary, and what capacity wheel?_ Twenty actual horsepower will be 20 x 4/3 = 26.67 theoretical horsepower. Formula: 33,000 x Hp. required (D) [...](image) (image)

Let us attack the problem of water-power in another way. _A farmer wishes to install a water wheel that will deliver 10 horsepower on the shaft, and he finds his stream delivers 400 cubic feet of water a minute. How many feet fall is required?_ Formula: 33,000 x horsepower required (C) Head in feet = —————————— Cu. Ft. per minute x [...](image) (image)

Water wheels are not rated by horsepower by manufacturers, because the same wheel might develop one horsepower or one hundred horsepower, or even a thousand horsepower, according to the conditions under which it is used. With a given supply of water, the head, in feet, determines the size of wheel necessary. The farther a stream of water falls, the smaller [...](image) (image)

By one of the above simple methods, the problem of _Quantity_ can easily be determined. The next problem is to determine what _Head_ can be obtained. _Head_ is the distance in feet the water may be made to fall, from the Source of Supply, to the water wheel itself. The power of water is directly proportional to _head_, just [...](image) (image)

Weirs are for use in small streams. For larger streams, where the construction of a weir would be difficult, the U. S. Geological Survey engineers recommend the following simple method: Choose a place where the channel is straight for 100 or 200 feet, and has a nearly constant depth and width; lay off on the bank a line 50 or [...](image) (image)
