is it the pressure balancing that we make on branch line junction points or in other words is it like, by selecting bigger pressure of two intersecting branchline and arranging the flow by K factor of the junction for the less pressured branch line ?
But in that case, how can 0.5 psi difference...
NFPA 13 - 22.4.2.4 states that "Pressures at hydraulic junction points shall balance within 0.5 psi (0.03 bar)" . I was not able to clarify what it refers to. On an elbow or on a tee how am i going to do that ?
NFPA 20 indicates that; (2003 ed. ) ,
5.14.6.3 Elbows and Tees.
5.14.6.3.1 Unless the requirements of 5.14.6.3.2 are met, elbows and tees with a centerline plane parallel to a horizontal split-case pump shaft shall not be permitted. (See Figure A.5.14.6.)
5.14.6.3.2 The requirements of...
Hi all,
we have to do calculation for a sprinkler system. But we have upright sprinklers in concealed spaces below ceiling with in the sprinklers protecting the room ( as in FIGURE 8.14.19.3.3 of the NFPA 13 -2003 ed) . For the hydraulic calculation shall i have to consider all these suspended...
Hi All,
We are planning to install a Deluge Foam-Water sprinkler system in an ( Group 1 - Acc. to NFPA 409) Aircraft hangar.
In NFPA 409 chapter 6.2.8.2.1 it's said that, for actuating the deluge system rate of rise, fixed temperature or rate compensation type detectors shall be used...
Dear 2610 (Ganesh)
Check with your advisor. I guess that the proper modelization of the structures you're working with is an important part of your thesis work. Give a chance to RAM Advanse, it's an easy to use structural program that has several load tools that I guess would help you.
