The diameter of the fixed pipe installation that supplies water to the sprinkler system should be determined according to the hydraulic calculations to be made.

The building we sample is the hotel. In each of the points in the critical line in the 2-line table direction and in the lines outside the critical area, only the number of points with the diameter change is given. The following illustration shows the critical area.

You can download the file as dwg. In this section we need to find out by means of the total debial balancing method which will provide 2 lines of pressure. If it were not for the same, we would have to recalculate these merging lines. In this section, we need to find the new press release method according to the biggest press to provide the appropriate press in these lines. As far as the greatest pressures 1, 2 and 3 are concerned, 3 are the lines.

Because 1 and 2 are the same, you can not give this number different numbers if you do not want to print, but you do not have to number them extra if the pressures are the same.

In this section, we need to find the new press release by balancing according to the greatest press to provide the pressure for these lines.

The maximum pressure is 1, 2 and 4 and 4 is the line. If you pay attention after you have done the balancing process, you will notice that there is no new flow and balance calculation from now on the critical hattan in this project. If there is only a change in diameter, we will calculate the pressure losses in these areas.

Otherwise, there is no point in getting a critical area. If the pressure loss value is high, increasing the diameter will lower the diameter. For this reason, it is not right to choose the main line diameter especially by looking at the table, it is necessary to determine the correct diameter by hydraulic calculation.

In this case, the correct and unnecessarily large diameter will not be selected.

In addition, there is a fire cabinet, a hydrant and a sprink system in your fire system. For pressure loss, we found sample sprink pressure loss of 41 ms, in other cases, for example firefighter 65 ms, hydrant 80 mss.

However, the correct pump selection must be made by looking at the pump curve. As the flow rate increases, the pressure loss decreases. As the flow rate decreases, the pressure loss increases.

Choosing the direction of the pump curve will help you save energy by preventing you from choosing a pump at high capacity.

These spreadsheets below will make your job much more easier, alowing you to shorten the time used for endless calculations of cables, voltage drop, various selections of circuit breakers, capacitors, cable size and so on. Spreadsheets are mostly developed by expirienced electrical engineers and programmers thank you mr. Jignesh Parmar! They all really did an awesome job, you must admit! With above settings, can anybody suggest why incomer feeder tripped during outgoing feeder cable fault?

Although I am not an electrical engineer but an electronics on I appriciate your contribution. Some subjects are very similar between the two careers. I have downloaded a few of the spreadsheet. They are so helpful. Can you please make one for vector group calculations. It must be able to draw the grouping as you put the figures on the spreadsheet.

It would be a more useful spreadsheet if you can actually size the loads for a residential home. Thanks, John. Dear Sir, we need a Dc cable Calculator for find out the size of cable for varies DC motor or invertor. I am requested to prepare excel sheet for calculating per unit value for common base particularly MVA base for transformer, transmission line for all conductors. Thank You very much. Your article is of great help to me as an electrical engineer. It will surely boost my electrical strength.

These sheets are fabulous.

Firefighting Design Calculations as per NFPA The National Fire Protection Association Doing a designing of fire fighting system is a most important part in any construction to ensure the safety of the peoples during usability of structure.

Computer programs can provide you with pages of information at the click of a mouse. However, given the demand for new sprinkler designers, there is a need to return to the basics. Designers, particularly newer designers, cannot be sat in front of a computer and be expected to get it right and understand sprinkler design the first time opening a program.

Designers must understand the steps to be taken to ensure the sprinkler system will be adequate for a given facility. Designers, many times, have to read and interpret specifications, reports, and drawings before beginning the design process within the various computer programs available to companies.

Given the number of steps that must be taken in order to design a sprinkler system, that provides a lot of room for error. Additionally, the steps are additive. The decisions made in one step will impact each step down the line. Therefore, it can be inferred that the first few steps the designer takes in the process are, arguably, the most important. The designer must first define the occupancy and then move forward to determine the appropriate design area and density for the system.

Furthermore, the designer must understand how to locate the design area within the system. These steps should be completed before the computer calculation program is opened. Occupancy Classification The first step in the design process is determining the occupancy in which the system will be designed Brock, However, this step is not always as straightforward as one may think. The occupancies within NFPA 13 have unique definitions. For instance, one manufacturing occupancy, as defined by the IBC, may not be the same occupancy classification within NFPA 13 as a different manufacturing occupancy.

Per NFPA 13, areas within a building will be defined as a light hazard, ordinary hazard Group 1ordinary hazard Group 2extra hazard Group 1and extra hazard Group 2.

To add to the confusion, there are then special occupancy classifications of Chapter 22, particularly storage commodity classes Class I through IV and plastic groups Groups A-C. While the Annex has a list of examples of each type of occupancy, it is not all-encompassing. Designers must make judgment calls on what some occupancies should be classified when it does not fit easily into one of the occupancy classifications.

Furthermore, many drawings use room names that may need to be interpreted regarding the actual use of such room. When designing for large warehouses, one must classify what is being stored. This is important as, many times, the owner or operators of these warehouses may not be fully aware of what is in the products.

There are differences in the compositions of the different plastic groups as defined by NFPA In addition to understanding what is being stored, one must also know how it is being packaged.

Warehouses also have the element of storage configurations from piles to racks to aisle widths. There is no one answer for all situations when designing a sprinkler system.Upon purchase, please send an email to rjneubert aol. We offer email support for your systems: rjneubert aol.
