# Would I have to add any additional weight at the end of the lever of well pump (B) for it to lift the same amount of water as did well pump (A)?

The question is if I would have to add any additional weight at the end of the lever of well pump (B) for it to lift the same amount of water as did well pump (A)? My assumption is yes because of friction but really I'm very unsure!

Both wells have different dimensions but with the exact same amount of water (1000gallons), & the amount of water being lifted is also the same per lever stroke. The wells are drawn up as:

Well pump#A) 10x500x10

Pump piston at the bottom only lifts 5ft high and is 10x5x10 in both wells.

Well pump#B) 3x500x3

Pump piston at the bottom portion of the well is 10x5x10.

The friction I speak of will occur once water is being lifted from out of the bottom wider portion of the well which is (10x5x10) up into the smaller portion of Well#B which is (3x500x3)

EXTRA: The lever does move slowly. Thanks!
