For calculation of requirement of fire f ire water for light and ordinary hazard we consider one major fire at a time and for high hazard we consider two major fires simultaneously. We consider water requirement for process area 1 LPM/M 2 For tank cooling we consider 10.2 LPM/M 2 We follow OISD for oil industry. For calculation of capacity of fire water reservoir it is given in TAC and NBC according to type of building. In TAC hours are also mentioned if we know hours and pump capacity (given in different tables on the basis of hazard and numbers of fire hydrants) we can calculate capacity of fire water reservoir. If we have to fight fire of only one area we can calculate how much water required Example: If pump capacity is 273 M 3 /hrs. = 4550 4550 LPM If this water coming through 150 mm diameter (06’’) pipe Maximum flow capacity of this pipe if we assume velocity 3 M/sec. (For fire water network we assume water velocity = 3 M/sec.) Q = A * V = 3.14 d 2 * V/4 D = 150 mm = 0.15 M V = 3 M/sec. Q = 3.14 * 0.15 * 0.15 * 3/ 4 Q = 0.0529875 M 3 / Sec. = 0.0529875 * 1000 * 60 LPM Q = 3179.25 LPM As it is known that discharge of landing valve of fire hydrant is approximate 900 LPM If we operate two landing valve then discharge will be 1800 LPM Remaining discharge is 3179.25 LPM - 1800 LPM = 1379.25 LPM We can operate two hydrants and one monitors if hydrants and monitors are in 150 mm line. As discharge of landing valve is 900 LPM but we connect hose and branch and water will consume according to the discharge of nozzle. So we can use two hydrants and one monitors if hydrant line is 150 mm diameter. If diameter of hydrant line is 200 mm Q = 3.14 * 0.2 * 0.2 * 3/ 4 Q = 0.0942 M 3 / Sec. = 0.0942 * 1000 * 60 LPM Q = 5652 LPM If we operate two landing valve then discharge will be 1800 LPM Remaining discharge is 5652 LPM - 1800 LPM = 3852 LPM In this situation we can operate two hydrants and two monitors of 1800 LPM (aprox.)
