A method to model a complex system of pipes. The model takes into account the physical processes in a tree-type piping system and provides for an accurate modeling of a real world tree-type piping system. In a preferred embodiment, a computer program is provided for analyzing models of dry pipe systems. The computer program includes a user interface and a computational engine. The user interface allows a model of a dry pipe system to be defined and the computational engine determines a liquid flow time through the model of the dry pipe system. The computational engine provides a verification of the liquid flow time in a model of a referential dry pipe system within 20% of an actual liquid flow time in the referential dry pipe system.

System and method for evaluation of fluid flow in a piping system

A method of and a computer program for analyzing models of dry pipe systems. The computer program includes a user interface and a model generator in communication with the user interface. The method and computer program provide for modeling a referential dry pipe system as a plurality of interconnected nodes, the nodes corresponding to a pipe connector, the interconnection between the nodes corresponding to a pipe device. The plurality of nodes can define a dry portion and a wet portion with the wet portion including a liquid source and the dry portion including a plurality of interconnected pipes to define a volume of gas. The nodes in the dry portion can define a set of nodal devices open to ambient. The method and computer program can provide for computing fluid time based parameters to simulate the liquid flowing from the wet portion to determine at least flow time of the liquid from the wet portion to the open devices. The method and computer program can provide for verification of the liquid flow time in the model within 20% of an actual liquid flow time in the referential dry pipe system.
