...through a fluid, is as the fquare of the velocity : and (putting i>— velocity in feet, in a fecond,) it is equal to the weight of a column of the fluid, whofe bafe is the plane, and height -— . And in a globe it , 04 is but half fo much. 5. The friction...

...moving through 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...

...of the fluid. 271. 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 PROPOSITION...

...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 acquire...

...portion of furface, is equal to the produit of that portion by the depth and denfity of the fluid : or it is equal to the weight of a column of the fluid whofe bafe is the given furface, and the altitude equal to the diftance between the furface of the...

...to the weight or pressure which generates that motion ; and this is equal to the weight or pressure of a column of the fluid, whose base is the area of the plane, and its altitude that which is due to the velocity. 398. Carol. 1. If a denote the area of the plane, v...

...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 a...

...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...

...pressure of a fluid against any upright surface, as the gate of a sluice or canal, is equal to half the weight of a column of the fluid whose base is the surface pressed, and its altitude the same as the altitude of that surface. 7. The pressure of a fluid,...

...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 own...
