2018年4月11日 · Since then I've tinkered and come up with an accurate chart that takes flow test input values, calculates total flow and draws the curve along the N^1.85 chart. The N^1.85 chart is particularly useful for fire suppression systems because the Hazen-Williams formula is based on the relationship that pressure relates to flow to the 1.85th power.

2022年12月23日 · English: This graph paper is commonly used to display the water supply and fire sprinkler system flow and pressure demand. It is called N185 graph or N1.85 graph paper. This file is made available under the Creative Commons …

/* The purpose of this Processing sketch is to display and optionally to save in scalable vector graphics (svg) file format a graph sheet used to show water supply and fire sprinkler system water demand. This graph is typically called N185 paper or N^1.85 paper.

The World's First Web-Based Hydraulic Graph N^1.85 for Water Supply and Demand Information .

2014年7月24日 · Abstract: N70 and N185 are two large ($\ge$100 pc in diameter) shell nebulae in the Large Magellanic Cloud (LMC). Their high [\ion{S}{2}]/H$\alpha$ ratios rival those of supernova remnants (SNRs), but they are not confirmed as SNRs.

Summary: This app provides a N^1.85 logarithmic graph based on NFPA 291 recommendations. Edit any field and the rest will update automatically.

The N1.85 hydraulic scale is used in hydraulic studies, particularly for fire suppression systems.

2014年6月25日 · A little background, hydraulic n1.85 graphs are used in the fire protection industy to graph the flow and pressure of a water supply (city, storage tank, etc) and the flow and pressure required (demand) by a building's automatic sprinkler system in order to compare them and see if the supply meets the demand or if a fire pump needs to be installed.
