PowER.-Another kind of water-wheel lias b ee n recently and extensively introd uced, whieh is ope rated by the re-action of a stream of water, which is forced into the centre of the wheel, and thence horizontally out through several apertures in its periphery ; hence this wheel is called the re..acting water-wheel. The motion of tllese wheels, is hori zontal, and the apertu res by which the water es capes are so arranged that the direction of the es caping water is nearly parallel to tae p erip hery ; and as considerable Torce is required to overcome the inertia of the wa te r, and force it rapidly out of the wheel i n directions contrary to that. in which the wheel is supposed to be moving, so there must ne cessarily be a correspon di n g re-action on the inte rior surfaces of the wheel w h ich i mpels it i n the d i rection contrary to the motion of the water. The greatest quantity of power that can p o ssi bly be d e rived frem a .fall of water by wheels of this kind, however, is somewhat less than one fourth part of the whole power of t11e water. If tht', head of wa ter be eight fect, o r four I bR . per square inch, and each aperture is equal to fou r square i nches, then i f the whole weight or w a t e r be applied to force i t sel f o u t thro u g h the said a p e rtu re s , while the wheel re mains s tati on ary or at rest, the re-action would be 16 I b s . , or nearly equal to the press u re ; and the ve loc i ty 01' t h e water through th e apertures w o u ld be at the ra te of about 20 feet per second. But if the wheel is ill Illotion equal to 10 fee t per s e c ond equal to h a l f of the natural velocity of the water, which is in fact the most advantagfous motion that a re-acting wheel can have-lhen the actual mo tion of the escaping current, is redu ced to ten feet per secolld alsl) ; all J as the re-act'ion of a fluid al ways corresponJs to the resistance M i ne rtia, and to itli momentum ; and as the momentum of a fluid with a velocity o f 10 fe et per seeotld i s o n l y one -aurth of that of 20 leet per seco nd, i t follows that f the r e -a c ti on of the water on t.he wheel when in motion, is o n l y 4 I bs., or one fourth of that on a wheel at rest. T his is not the (Jnly disadvantage 'of a re-acting wa ter wheel ; fo r in most cases the wa ter is made to c ua nge its direction by an angle, at least once before reaching the centre of the wheel ; and again in p a ss ing thence to the apertu res ; and in each of the changes of direction nearly one fourth of the m o m e n tu m of the wa te r is lost. Be sides this, if the p e nt-s loc k or Bpout that conducts the water to the wheel, is not very large, there will be a considerable part of the power of the water lost by chok i n g in the channel _ This theory would bring the power of a re-ac.. g wheel, to correspond nearly, with th e result of an experiment on a re acting wheel ily Ol i ve r Evanlt-which was on e 9th of the whole power of the wate r. In treating of these several disadvantages, however, it may be observed that we have m ad e no allowance for any riction 01 the water, in p assin g through ilie chan f nels, &c. We consider the friction of a fluid i n p ass ing through a st rai gh t or curved smooth chan nel, to be merely nominal nothing to be discovered.

We m ay not be a ble to m ak e this case clear to o u r respected correspondent. As we have said be fore, this point in natural philosophy, is v e ry difficult to demonstrate, although it is fully es tabl is he d by experiment. To the first quelition in the above, we answer, No ; for if the man, while projecting the apple, stands firmly on the floor of the car, he Itill exer t!! two powers, one of which is applied to the apple, and the other, in re- action, on the car, which deprives the car of part of its momentum. We ad mit that in this case the bodily exer t ion is less, be cause a less relative motion is r equ i re d : but ilie a c tual power applied is the l!Iame. In answer to the s e co n d question, we would say that if the man stood on ice, in the 6rst instance a dou bl e power would be required i n effe cting the first proj ec ti on. We are aware that this opens the way for the argument that a double power would also be e x e rted , even iI he stood on fi rm earth in the first instance, because one powe r is applied by re-action, to t h e earth ; an d on this ground it would appear that si:c powers, in stead of f o u r, are requh'ed to produce double velo city. But the fact is, that when a power of re-ac tion is a p plie d to the earth-terra 6rma-it is never brought into the account : otherwise, every single vel6city would re qu ire a d ou b l e power, and a double velocity would require the exertion of six powers not 8-instead of four. The reason why six pow ers only, instead 01 e ig h t, are exerted in this case, is because the duration o f the re-action against the carili, is only half as long, as in case of a single ve locity projection ; and the power elFerted in re-ac tion must be in pr opo rti on to the time multilJlied by the f orce appli ed, and not acco rd i n g to the force alone. But, as before remarked, no allowance is made for re-action against the e ar th , or any per manent object.
