For the following network:
a) Determine the pipe diameters, if the maximum-allowed hydraulic gradient Smax =
0.005. Determine the surface level of the reservoir at the supply point, which can
maintain a minimum pressure of 20 mwc. Assume for all pipes that k = 0.05 mm and
the water temperature is 10° C.
b) For the calculated surface level in the reservoir, determine the pressures and flows if
the demand in nodes 6 and 7 has increased for 10 l/s. Change the pipe diameters
where necessary in order to meet the design criteria (Smax and pmin/ρg).
