Question

A suction pump at ground level can draw water from a well whose depth of water level is (A) more than 40 feet (B) less than 35 feet (C) about 50.8 feet (D) none of the above

The water can be drawn from a well whose depth is equal to height of water column (= 76 cm of mercury column). ∴ h=hρ text/ρ 1 =(76× 13.6/1) =1033.6 cm =(1033.6/2.54× 12)ft =33.91 ft Thus, depth of water level is less than 35 feet.

The water can be drawn from a well whose depth is equal to height of water column (= 76 cm of mercury column). $∴$ $h = h ρ / ρ_{1}$ $= \frac{76 \times 13.6}{1}$ $= 1033.6 c m$ $= \frac{1033.6}{2.54 \times 12} f t$ $= 33.91 f t$ Thus, depth of water level is less than 35 feet.
