...square vessel with vertical sides is filled with water, the pressure against the vessel's sides is equal to the weight of a column of water whose base is the surface, and whose height is the head of water upon that surface. If the gate A, fig. 46, is four feet...

...of water in pounds), and dividing by 64£, the pressure upon a surface moving in a fluid being equal to the weight of a column of water whose base is the area of the surface, and the altitude equal to the space, a heavy body must fall through to acquire...

...Cold, fcc. London : 1663. > that the direct pressure which a body steeped in water supports is equal to the weight of a column of water whose base is the upper surface of this body, and the height that of the water placed above that surface. He showed that...

...of the play below the spout. The difference between these pressures is exerted upwards, and is equal to the weight of a column of water whose base is the area of the piston, and whose altitude is the distance from the middle of the play to the spout. The...

...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 side. If water is poured into the tube, there will be a pressure on the bottom of the cask equal to the weight of a column of water whose base is the bottom itself, and whose height is equal to that of the water in the tube. The pres*<8< may be made...

...Efficiency of a Reciprocating Pump. — We have shown that the load upon the piston of a pump is equal to the weight of a column of water whose base is the area of the piston, and whose height is the vertical distance from the surface of the pool to the point...

...following rule will be generally applicable, viz.: the pressure of water against a plane surface is equal to the weight of a column of water, whose base is the surface and whose height is its head of water. EG, if the other circumstances are the same, a wall...

...similar train of reasoning to that employed above shows that the resultant horizontal pressure is equal to the weight of a column of water whose base is the projection of the surface of the body on a plane at right angles to the horizontal line, in the direction...

...common suction pump, explain fully its action, and prove that when in regular action the force necessary to raise the piston is equal to the weight of a column of water whose base is the area of the piston, and whose height is the height through which the water is raised. 11. Prove that...
