...a fluid is as the square of the velocity; and putting r~ velocity in feet in a second ; it is equal to the weight of a column of the fluid, whose base is the plane, and height — . And in a globe 64 it is but half so much. 5. As to the mechanic powers,...

...The Real Resistance to a Plane, by a Fluid acting in a Direction perpendicular to its Face, is equal to the Weight of a. Column of the Fluid, whose Base is the Plane, and ^Altitude equal to that which is , due to the Velocity of the Motion, or through which...

...Ee were a plane surface moving perpendicularly in a fluid, the resistance against it would be equal to the weight of a column of the fluid whose base is the surface resisted, and altitude the space through which a body must fall from rest, in vacuo, to...

...and its altitude the same as that of the surface. Or, by art. 31* of the same, the pressure is equal to the weight of a column of the fluid, whose base is equal to the surface pressed, and its altitude equal to the depth of the centre of gravity below the top or surface...

...fluid. S09. Carel. 309. Carol. 3. The pressure of the fluid on any horizontal surface or plane, is equal to the weight of a column of the fluid, whose base is equal to that plane, and altitude is its depth below the upper surface of the fluid. 'PROPOSITION LXI. 310....

...The Real Resistance to a Plane, by a Fluid acting in a Direction perpendicular to its Face, is tqual to the Weight of a Column of the Fluid, -whose Base is the Plane, and Altitude equal to that -which is due to the Velocity of the Motion, or through -which...

...last proposition, the whole pressure sustained by any portion whatever of the bottom or sides of the vessel, is equal to the weight of a column of the fluid having for its base the surface pressed on (extended into a plane if necessary), and for its altitude...

...act against a plane in a perpendicular direction, the real or absolute force on the plane is equal to the weight of a column of the fluid whose base is the plane, and height equal to the height through which a heavy body must descend from rest by its...

...demonstrated that the resistance of a cylinder, which moves in the direction of its axis, is equal to the weight of a column of the fluid, whose base is equal to that of the cylinder, and its altitude equal to the height through which a body must fall in vacuo,...

...resistance opposed to a plane surface moving in a fluid, in a direction perpendicular to the plane, is equal to the weight of a column of the fluid, whose base is the area of the plane, and height the space through which a body must fall by gravity to acquire its...
