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 1500 m 1505 m 1485 m 1475 m 1500 m 1505 m 1485 m 1475 m 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 400 450 600 500 400 450 600 500 ANSWER DOWNLOAD EXAMIANS APP
