从AutoCAD中的简单LISP命令开始,此HAVC管道大小计算器已迁移到独立的Java应用程序。 根据GPM和FPS计算多种流体类型的HVAC最小管道ID(可在EngineeringToolbox.com上的流体密度图表中找到)包括一个表格,该表格可自动计算每层楼板的立管尺寸。 阅读PipeSize.zip中包含的README.txt文件以获取说明。
Overall head loss in a pipe is affected by a number of factors which include the viscosity of the fluid, the size of the internal pipe diameter, the internal roughness of the inner surface of the pipe, the change in elevation between the ends of the pipe and the length of the pipe ...
Pipe Weight Calculator Weight calculating equation for steel pipes. Weight of Empty Pipe Weight of empty pipe per unit length can be calculated as wp = ρm Am = ρmπ (do2 - di2) / 4 = (π / 4) ρm (do2 - di2) (1) where wp = weight of empty pipe per unit length (...
then (10 gpm/9.5-gpm)^2 (squared) = 1.108, or the proportionally greater pressure loss your length of pipe will see as a result of the greater flow. Multiplying 2.6-psi by 1.108 = 2.881 is the calculated loss for 100-feet of your pipe ...
NPS - 'Nominal Pipe Size' and DN - 'Diametre Nominal' The size of pipes, fittings, flanges and valves are often given in inches as NPS - Nominal Pipe Size, or in metric units as DN - 'Diametre Nominal'. Pipes are made of a wide variety of materials - like galvanized steel, bla...
velocities of liquid passing through piping. Velocity is constant for a given flow rate and independent of pipe length. Pipe diameters are selected to achieve a velocity of 5-10 feet per second. Chart versions of the data used to build this calculator are also available.Schedule 40or...
