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 400 450 500 600 400 450 500 600 ANSWER DOWNLOAD EXAMIANS APP
Water Supply Engineering Corrosion of well pipes may not be reduced by using screens having larger area of openings using thicker pipes reducing the draw down and the pumping rate reducing the flow velocity using screens having larger area of openings using thicker pipes reducing the draw down and the pumping rate reducing the flow velocity ANSWER DOWNLOAD EXAMIANS APP
Water Supply Engineering The R.L. of ground water table on the sides of a valley is 1505 m whereas R.L. of the stream water is 1475 m. If 60° slope consists of pervious soil between R.L. 1485 m to 1500 m, the gravity spring may be expected at the point of reduced level 1505 m 1500 m 1485 m 1475 m 1505 m 1500 m 1485 m 1475 m ANSWER DOWNLOAD EXAMIANS APP
