Water Supply Engineering While determining the yield of open wells by the pumping test Velocity of recharging water, increases with depression head Maximum safe yield of an open well, is expected at critical depression head Working head is generally limited to ?rd of the critical depression head Depression head resulting at critical velocity, is called critical depression head Velocity of recharging water, increases with depression head Maximum safe yield of an open well, is expected at critical depression head Working head is generally limited to ?rd of the critical depression head Depression head resulting at critical velocity, is called critical depression head ANSWER DOWNLOAD EXAMIANS APP
Water Supply Engineering Corrosion of well pipes may not be reduced by using screens having larger area of openings reducing the flow velocity reducing the draw down and the pumping rate using thicker pipes using screens having larger area of openings reducing the flow velocity reducing the draw down and the pumping rate using thicker pipes ANSWER DOWNLOAD EXAMIANS APP
Water Supply Engineering To pump water from a water reservoir 3 m deep and maximum water level at 135 m, a pump is installed to lift water up to R.L. 175 m at a constant rate of 36,00,000 litres per hour. If the length of the pipe is 1506 m and f = 0.01, ignoring other minor losses and assuming the economical diameter from Lea's formula D = 1.2 √Q, the water horse power of the pump is 600 400 450 500 600 400 450 500 ANSWER DOWNLOAD EXAMIANS APP
