Larger trees are more fire-resistant ...
Background and aims: Providing the adequate flow and water pressure in the firefighting network of the power plants requires the proper design and analysis of the firefighting system. This study aimed to model and hydraulic analysis the fire network in a combined cycle power plant to determine the network efficiency in the extinguishing of the possible fire. Methods: In the present study, the ...
