Approximate Weight Spiral Duct In pounds per linear foot - Based on galvanized steel. Pipe Weight Formula - This formula can be used to determine the weight per foot for any size of pipe with any wall thickness. Round ductwork is subject to duct suction collapse, and requires stiffeners to minimize this, but is more efficient in material than rectangular duct work. Specifications Operating and proof pressure 15 and 22.5 psig immersed in 130ºF water Vacuum either formed as part of the lay-up -13 psig Temperature variation procedure or are mechanically Per RTCA/DO-160D, section 5- modified Temperature shock -40ºF followed by immersion into 60ºF water duct surface area in square feet per lineal foot a.7 galvanized sheet weight a.8 approximate weight-round duct in pounds per lineal foot a.10 area and circumference of circles a.11 angle, bar & channel properties a.12 2″ w.g. To determine the weight per foot of any piping insulation, use the pipe size and nominal insulation thickness to find the insulation weight factor F in the chart shown below. Divide by 144 to determine how many square feet are in the duct area. Add 10% for insulated ductwork systems. Multiply the number of pounds per linear foot by the number of linear feet to determine the total number of pounds. CFM: It is a unit to measure the velocity of the flow of air and can be expressed as ft 3 /min. We can determine the volumetric flow rate as follows: The flow rate will vary according to the cross-sectional area of the channel: Area = π * (Diameter) 2 / 4. 60,000 Q&A topics -- Education, Aloha, & Fun topic 51726 What is the pound per linear foot on 26GA through 14GA Galvanized Metal March 26, 2009. 11 approximate weight spiral duct in pounds per linear foot based on galvanized steel''Square and Rectangle Weight Per Foot and Bundle Chart May 2nd, 2018 - Square and Rectangle Weight Per Foot and Bundle Chart 6226 West 74th Street Chicago IL 60638 1 800 376 6000 1 708 563 1950 FAX itctube com www independencetube com' Front of calculator includes scales for friction, velocity, round duct size, weight per linear foot of round duct, surface area in square feet per lineal foot of round duct, rectangular equivalents of round duct sizes, weight per linear foot of rectangular duct and surface area in square feet per linear foot of Rectangular duct. ’ ve got our handy weight calculator here conditions, and seams duct in per... 1 ) units of height and width of a duct the channel at an average of $ $!
