, butwill be made clear by considering that with a given surface, when the velocity is doubled, twice thequantity of liquid will move through twice the space in the same time, and will therefore, accordingto the principles of mechanics, have a fourfold momentum. The resistance, therefore, offered… … 122 HYDROMETER. water with a velocity of 32 ft. per second, meets with a resistance equal to a weight of 1,000 lbs.When the motion of a body in a liquid is very slow, say less than 1 in. per Becond, depending on thesize of the body, the larger body requiring to move more slowly, the above laws are…
