Question
(a)
An open domestic hot water circuit for a residence is to cater for three bathrooms each having two
hot water outlets of diameter 20mm. All outlets are connected to a single main line pipe running
down the service stack shaft. After factoring all friction losses and the gravitational head, the system
is pressurised such that the ideal flow rate per outlet is 14 l/min. What is the ideal main pipe diameter
size if the fluid velocity in the main line pipe and the outlet branches is to be kept the same and
(i)
A diversity factor (i.e. the number of outlets open to atmosphere over total number of outlets
installed) of 0.5 is assumed (half of the taps open at any point in time)
A diversity factor (i.e. the number of outlets open to atmosphere over total number of outlets
installed) of 0.75 is assumed
(ii)
(ii)
A diversity factor (i.e. the number of outlets open to atmosphere over total number of outlets
installed) of 1.0 is assumed (All taps open at any point in time)
