estimate the service basin storage volume needed to meet both
the equalising demand and the fire reserve based on the shown
information. Hourly demands on the day of maximum water consumption
are given in the table and fire flow requirements are for 60 L/s
for a duration of 6 hours from the storage (midnight to 6am).
Determine the necessary pumping rate for:
a) A uniform rate over 24 hours.
b) A uniform rate from 10pm to 6am.
