What is the formula to calculate friction losses through intake conduits?
h f =FLV²/2g Ф
h f = 10.675 *L* (Q/c)1.852 Ф-4.87
h f = 0.1 * L
h f = Q / (n*π*Ф²)

To transmit raw water to the treatment plant
To store water
What is the design flow for maximum flow in transmission lines?
Qd (max) = 1.1 * Qavg
Qd (max) = Qmin * 2
Qd (max) = 1.1 * Qmm
