Q. A suction pump at ground level can draw water from a well whose depth of water level is

CMC MedicalCMC Medical 2007

Solution:

The water can be drawn from a well whose depth is equal to height of water column (= 76 cm of mercury column). $ \therefore $ $ h=h\rho \text{/}{{\rho }_{1}} $ $ =\frac{76\times 13.6}{1} $ $ =1033.6\,cm $ $ =\frac{1033.6}{2.54\times 12}ft $ $ =33.91\,ft $ Thus, depth of water level is less than 35 feet.
