Side 308 - ... length, and, 14-4 = ale gallons, and 14-4 X 282 = 4060-8 = the cubic inches in 12 feet length. The resistance which is opposed to a pump rod in raising water, is equal to the weight of a column of water whose base is the area of the piston, and height the height of the surface of the water in the body of the pump above the surface of the water in the well, together with the friction and the piston and piston rod.
Side 317 - A.EB; or the whole force exerted in the case, of equilibrium is equal to the weight of a column of water whose base is equal to that of the piston, and altitude the distance between the surface of the water and the point to which it is to be raised.
Side 67 - The reason is, all bodies lose some of their weight in a fluid, and the weight which a body loses in a fluid, is to its whole weight, as the specific gravity of the fluid is to that of the body. The...
Side 307 - ... quantity. The quantity of water discharged in a given time, is determined by considering that at each stroke of the piston a quantity is discharged equal to a cylinder whose base is the area of a cross section of the body of the pump, and height the play of the piston. Thus, if the diameter of the cylinder of the pump be 4- inches, and the play of the piston 3 feet, then, by mensuration, we have to find the content of a cylinder 4 inches diameter, and 3 feet high...
Side 317 - B p = x ; also put k = area of a section of the pipe AB, and mk = area of a section of the barrel AS. Now, let the piston be at A, then the elasticity of the air AP, together with the weight of the column of water BP, is equal to the pressure of the air, or is...
Side 203 - The pressure of a fluid on any surface, whether vertical, oblique, or horizontal, is equal to the weight of a column of the fluid, whose base is...
Side 27 - ... the weight of a column of fluid whose base is the area of the piston and altitude the difference of level between the...
Side 138 - If a square be inscribed in a circle and another circumscribed about both : compare the pressures upon the circle and the squares when immersed vertically in a fluid; the angular point of the circumscribing square coinciding with the surface of the fluid. 9. A hollow cone, whose vertical angle is 60°, is filled with water., and placed with its base downwards. It is required to determine the place where a small orifice must be made in its side, so that the issuing fluid may strike the horizontal...
Side 308 - The sum of the two is the height of a column of water, which the wind is capable of sustaining at that time...
Side 316 - PV on the lower surface of the piston is equal to the weight of a column of water whose base is equal to the section of the piston, and whose height is MN.
