Rule of Thumb for Flow Rate Through Hospital Sanitary Line
Rule of Thumb for Flow Rate Through Hospital Sanitary Line
(OP)
is there a rule of thumb for calculating the flow rate of sanitary sewer through a hospital sewer line? For example, X gallons per day per number of beds in a hospital. As a structural engineer, building codes typically have tables listing what loads are to be used for the design of hospital floors, libraries, offices, etc. etc. I was wondering if for plumbing design there was something similar for estimating the size and flow rate through pipes. Thanks.

Years ago the Institute of Plumbing used to work on a simple rule of thumb where you totalled the appliances (say 100) and you found the sq.rt. i.e. 10. This gave a quick guesstimate on the number of appliances that would be in use at any one time.
Nowadays, the simultaneoud demand tables yield slightly different results...but not usually that far out.

As for line sizing, the building code has tables based on flow and slope.
Hope this helps.

I worked on sizing air, vacuum, gas, HW, HWR, CW piping based on this reference.
Good Luck
