These basic procedures can also be used for calculating many other types of systems such as fire hydrant, hose reel or the discharge from a water cannon or monitor we can also use the same principal for almost all other water-based fire protection systems if we have a k-factor for the output device (fire sprinkler, water mist nozzle and so on).A tree system is end feed, that is water is only fed from one direction as opposed to a grid or loop system when water may arrive at the sprinkler head from more than one direction.We have dimensioned the pipe lengths and given each junction point a unique node reference number which we use throughout the calculations.
We can also see that the minimum sprinkler pressure of 0.5 bar is not sufficient to produce the required flow rate so the next step will be to determine what pressure will be required to produce the required flow of 76.50 Lmin at the first sprinkler head at node 130 we can do this by using equation 3. As the pipe has an internal diameter of 27.30 mm and has a C value of 120 this will give us. We now add this flow to the flow in the seconded pipe 120-110 to find the total flow in the third pipe 110-100 which will give us the flow of 244.20 Lmin. However, the last pipe has an internal diameter of 36.0 mm so this gives us.

With increased urbanization, and construction of complex infrastructures like advanced warehouses, factories, power distribution centers, refineries, multi-storied residential and commercial buildings, etc., having a good piping system is a must for supplying adequate amount of clean water for fighting against fire threats. Earlier, piping design was done by using many manual calculations and formulation methods. This made piping design a laborious and time-consuming process and it was also prone to large amount of errors. However, modern piping design is done by using software such as ANSYS, CFD, AUTOCAD, etc. In this paper, we highlight the requirements of a good piping system, and we elaborate upon the various steps involved in designing of such systems, and choosing the suitable type of piping layout for the required conditions such as available pressure, consumption demand, flow rate, etc. Grid Pattern with Loops: This type of pipe layout is a modified type of Grid pattern layout (Figure 12). In this layout, loops are provided in a grid: Water flow in Loop system 2 Software generated report for loop system (screen-shot) 4. Hydraulic Analysis (Of Distribution Systems):-After the suitable type of pipe layout is chosen, the next and final step involves the analysis of the chosen layout. This involves calculating the flow rate, supplied water pressure, volume, losses, etc. The calculation process is done using hydraulic analysis software like SprinkCALC, PipeNET, SprinkCODE etc. These softwares are designed especially for calculations of piping for fire protection systems.

This not only red uces the com putation times, but also allow s us to have a virtual sim ulation of the chosen design, ther eby giving us a better idea abou t how effective the chosen piping design will be before it is im plemented, thus allowing us to fine tune the design for better output and a lso reducing the errors.

I. I NTRODUCTION Piping Network is a system of pipes and trench es which provide the appropr iate quality and quantity of water to a community. The design, construction and layout of the piping network have to be carefully prepar ed in order to ensure that there is enough flow pressure to supply hygienically safe water. On ce the network is constructed, its maintenance has to be performed, which includes repairs, leakage control, prevention of recontamination, etc. Along with mainten ance, the proper operation of pum ping stations has to be ensured for areas where gravity pressure alone is not enough (Figure 1).

T HEORY Figure- 2: System design vs water flow direction Requirements of an Adequate Distribution System: For an ad equate water d istribution system, the r equirements are as follows: 1. Water quality should not deteriorate while flowing through the distribution pipes. The system should be capable of supplying water to all the intended places with sufficient pressure head. It should b e capable of supplying the required amount o f water during firefighting. The layout shou ld be such that no consum er is without water supply, during the repair of any section of the system. It should be fairly w atertight to minimize losses due to leakage.
