Calculation of Fire Water Tank
Introduction The water supply in the fire water main ring shall be sufficient to supply the maximum required fire protection water demands for at least 2 hours system operation. The required amount of the water shall be based on the requirement to supply the following system by a simultaneous operation of:-
a) b) c) d)
Two(2) nos. of outdoor hydrants One(1) One(1) no. no. of foam foam monitor monitor One(1) no. of of fu fuel oi oil ta tank spray sy system One(1) no. of of fue fuell oi oil ta tank fixe ixed foam syste ystem m
