Seite 26 - All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, thither they return again.
Seite iii - QC A New, Revised, and considerably Enlarged Edition (the 6th), with very numerous Illustrations. 4s. 6d. cloth limp; 5s. 6d. cloth boards, gilt. 82. THE POWER OF WATER, as applied to drive Flour Mills, and to give motion to Turbines and other Hydrostatic Engines.
Seite 2 - No man shall take the nether or the upper millstone to pledge : for he taketh a man's life to pledge.
Seite 3 - Cease your work, ye maids, ye who laboured in the mill : sleep now, and let the birds sing to the ruddy morning, for Ceres has commanded the water nymphs to perform your task ; these, obedient to her call, throw themselves on the wheel, force round the axle-tree, and by these means the heavy mill.
Seite 66 - ... and, consequently, all those powers are equal, whose products, made by such multiplication, are equal : for if a power can raise twice the weight to the same height, or the same weight to twice the height, in the same time that another power can, the first power is double the second : and if a power can raise half the weight to double the height, or double the weight to half the height, in the same time that another can, those two powers are equal. But note, all this is to be understood in case...
Seite 77 - ... inches, and there impinging upon another body, would be capable of producing an equal effect by collision, as if the same cubic inch had descended through the same space with a slower motion, and produced its effects gradually ; for, in both...
Seite 69 - It is somewhat remarkable, that though the velocity of the wheel, in relation to the water, turns out greater than -J- of the velocity of the water, yet the impulse of the water in the case of a maximum is more than double of what is assigned by theory ; that is, instead of -j- of the column, it is nearly equal to the whole column.
Seite 7 - Great for means of defence against his irresistible legions) would appear to be entirely with a view to raise water sufficiently at low seasons to give it impetus, as well as a more abundant supply to the wheels, and their effect at those times is to create a fall in every part of the width, save the opening left for commerce, through which the water rushes with a moderately irregular surface.
Seite 66 - The raising of a weight, relative to the height to which it can be raised in a certain time, is the most proper measure of power, or, in other words, if the weight raised be multiplied by the height to which it can be raised in a given time...
Seite 68 - ... less, they approach nearer to a coincidence ; and, consequently, in the large openings of mills and sluices, where great quantities of water are discharged from moderate heads, the head of water, and virtual head determined from the velocity, will nearly agree, as experience confirms.* • OBSEEV.
