=+garage. The load for the complex is expected to be quite variable from day to night

(a) In a two-dimensional sketch layout the secondary water distribution system from the main equip ment room to each building. The piping may be supported from the ceiling structure of the garage.

(b) In a separate sketch layout a constant volume primary, variable volume load sys-

tem consisting of three 500 ton (1758 kW) chillers.

(c) In another sketch layout a typical terti-

ary circuit to serve each building.

(d) If the system is to operate with water supplied at 45 F (7 C) and returning at 60 F (16 C), what are the capacities of the various pumps?

(e) What size commercial steel pipe will be required for the secondary circuit leaving and returning to the equipment room?
