Notes:
1.
Propane demand is based on a gas pressure at the
burner of 6.89 kPa except for the bilge and pit
fires which are based on 13.78 kPa.
2. The design propane demand for each building is:
B1 79 + 88 or 167 L/s
B2 9 + 9 or 18 L/s
B3 186 L/s
B4 186 L/s
3. The design propane demand for the four buildings
together is: 168 + 19 + 186 + 186 = 559 L/s
