Hydraulic Analysis of Fire Sprinkler Systems
The computer program SPRINK2000 was developed by ACADS-BGS of Melbourne Australia. SPRINK2000 is an adaption of the computer program SPRINK, developed by Municipal Hydraulics Ltd. and the University of British Columbia. The primary modification made to the program is a Windows interface that facilitates improved user interaction with the program.
The computer program SPRINK2000 may be used to analyze automatic fire sprinkler systems with simple end or side fed configurations, or more complicated looped and gridded systems. It may also be used to analyze fire hydrant and hose reel installations or a combination of sprinkler, fire hydrant or hose reel systems. SPRINK2000 can analyze any hydraulic system handling water where the discharge can be expressed as a "k" factor.
With a given sized network, the program performs a complete hydraulic analysis determining the water flow and pressure drop through each pipe in the network taking into account all data entered by the user. The user may provide for outflow from the network through operating sprinkler heads, hose or hose reel nozzles or standpipes (constant discharge point). With the facility to allow for outflow from standpipes, the program can also be used for the static hydraulic analysis of open circuit piping networks other than sprinkler and hydrant systems.
The main features of the program are:
- The program is capable of analyzing looped and gridded systems as well as the more conventional tree configurations.
- The program can be used to carry out an analysis of sprinkler systems, hydrant systems with or without hoses or hose reels in accordance with NFPA.
- The program can work in a wide range of units including Metric, and Imperial (British or US) and uses the Hazen-Williams formula for the hydraulic analysis.
- The program operates under WINDOWS and all input data is via a series of screens using using drop down lists and selection lists to facilitate easy data input.
- Nodes that are not discharges or input points are automatically assigned as reference nodes to save input, the user only having to assign elevations.
- Piping materials complying with a wide range of codes are catered for including light, medium and heavy steel, cast ductile iron, and copper piping to North American piping codes.
- When pipe sizes are entered as nominal sizes the program determines the actual inside diameter from data stored in the program. The user can however add to this list by entering their own pipe materials and associated internal diameters.
- A wide range of fittings are provided for with equivalent lengths stored in the program. A facility is also provided for users to add to this with their own fittings and associated equivalent lengths or to modify specific fittings by entry of alternative equivalent lengths.
