Since z/h could only be 0 if the sprinklers are attached at or below the base of the building, I think it best to show a more likely scenario.

What confuses me is where the minimum and maximum values for Fd are determined from. I know they refer to ultimate and working, and we are to use the working (or service value), but the equations to determine the service value confuse me. Where did it come from?
