For hydraulic calculation, a Hydraulic circuit needs to be built prior to hydraulic calculation. Also, you need to gather the required data (refer to 2.1) prior to doing hydraulic calculation you need to follow the below steps: Step-1, Select the loop whose hydraulic calculation needs to do. Step-2, Mark up the hydraulic loop in PFD then in P & ID.
5. Hydraulic calculations for sprinkler systems shall comply with NFPA 13 and shall include comprehensive hydraulic data sheets. Provide a 10 psi or 10% whichever is greater safety factor for all sprinkler system hydraulic calculations. 6. No work shall be performed until the University has approved the shop drawings, calculations, and data sheets.
The question is asking for the K-Factor, so we know to use: K = Q ÷ √P. Plug everything in, and our formula will look like: K = 28 gpm ÷ √18 psi. That leaves us with: K = 28 gpm ÷ 4.24 psi. Finally, after we divide, we get: K = 6.6. Hydraulic calculations become much more digestible when we know what is really going on behind the equation.
Simple Hydraulic Calculator . Introduction. Welcome to the Simple Hydraulic Calculator (SHC for short).SHC is a powerful, flexible, and full featured computer application for fire sprinkler hydraulic calculations. SHC was designed, from the ground up, for automatic fire sprinkler system designers and engineers.. To learn SHC, work through the "Getting Started" pdf.
The first sprinkler in the hydraulic calculations is so critical in getting it right. Residential, extended coverage, CMSA, and ESFR sprinklers start with a beginning pressure and flow. Other sprinklers have to be determined by taking the density times the protection area per sprinkler in Section 8.5.2.1.
with Factory Mutual Global Data Sheet 7-11, Conveyors, or equivalent. • The sprinkler design drawings and hydraulic calculations should be reviewed by ARC prior to installation. • Provide adequate drainage in order to prevent collapse of a conveyor gallery or system due to water weight from sprinkler discharge. Manual Fire Fighting
The first step is to calculate the minimum flow which will be required at the most remote sprinkler which in this case is at node [130], this is a two-step process as will need to calculate the minimum flow required to satisfy the 7.50 mm/min design density and then find the flow rate from the sprinkler given the sprinklers minimum pressure requirement, whichever is the …
6. Determine the minimum water supply needed to support sprinkler system demand. 7. Apply hydraulic principles to balance flows and pressure at junction points. 8. Describe the output of hydraulic calculation software and appropriate input to obtain an acceptable result and identify common errors.
Hydraulic calculations are a very important step when designing fire protection systems, since they ensure the flow rate established through the piping network will be enough to control fires effectively. Calculation procedures are established in model codes: automatic sprinkler systems are subject to NFPA 13 (National Fire Protection Association).
justments made should be noted on the hydraulic calculation to provide the AHJ with the purpose of the higher flow rate. Step 1. Calculate the required flow and pressure for the sprinkler selected using the standard formula Q= K√P. From the previous example: The sprinkler selected is …
edition, the requirement of performing hydraulic calculations in lieu of pipe schedules for the design of sprinkler systems was made more stringent. Section 5-2.2.1 of NFPA-13 says, "… Pressure and flow requirements for Extra HazardOccupancies shall be based on the hydraulic calculation methods of -2.3. The pipe schedule5

The calculation uses the formula for water flow through an orifice, based on the pressure inside the pipe: Q (flow) = 29.83 x C D x d 2 x √P C D is the discharge coefficient, which is based on the orifice characteristics and determined experimentally. On the other hand, the letters d and P simply represent diameter and pressure.
Hydraulic calculations are very important when designing fire protection systems, since they ensure that the piping delivers enough water to extinguish any fire. In particular, automatic sprinkler systems are subject to the NFPA 13 Standard in the US, and the equivalent international standard is EN 12845.. The hydraulic calculation procedure deals with three …
FHC is being used to hydraulically module an EN 12845 high hazard fire sprinkler system. The system is for roof protection only and is designed to provide 10mm/min density over 260m2. The model has 412 pipes, 30 loops and 31 operation heads (K80 min pressure of 0.5 Bar), FHC calculated this systems in 0.06 seconds.
