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 400 600 500 450 400 600 500 450 ANSWER DOWNLOAD EXAMIANS APP
Water Supply Engineering If the chosen diameter of a pipe, is less than the economical diameter Cost of pumping will be more than saving Head loss will be high All listed here Cost of pipe will be less Cost of pumping will be more than saving Head loss will be high All listed here Cost of pipe will be less ANSWER DOWNLOAD EXAMIANS APP
Water Supply Engineering While determining the yield of open wells by the pumping test 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 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 ANSWER DOWNLOAD EXAMIANS APP
