Water Supply Engineering Corrosion of well pipes may not be reduced by using screens having larger area of openings reducing the flow velocity using thicker pipes reducing the draw down and the pumping rate using screens having larger area of openings reducing the flow velocity using thicker pipes reducing the draw down and the pumping rate 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 400 500 450 600 400 500 450 600 ANSWER DOWNLOAD EXAMIANS APP
