...contraction of the length of the stroke. 643. The velocity of the water flowing from the sucking pipe iuto the barrel, should be equal to the velocity with which the piston moves. For if it be greater, legs work will be done than the pump is competent to effect ; if it be less, a vacuum will be produced... | |
