Wannear't S <= 6 mm, R-1.5S, de rekommandearre formule foar it berekkenjen fan it gewicht fan fjouwerkante behear teory wurdt werjûn yn fergeliking (A1);
As S>6mm, R = 2S, wurdt de oanrikkemandearre formule foar it berekkenjen fan it gewicht fan fjouwerkante managementteory werjûn yn fergeliking (A2)
G=0.015 7S (2A-2.858 4S) (A1)
G=0.015 7S (2A-3.287 6S) (A2)
Yn de formule:
G - It teoretyske gewicht fan in fjouwerkante stielen piip (mei in tichtheid fan 7,85 kg/dm3), yn kilogram per meter (kg/m);
A - Side lingte fan fjouwerkante stielen piip, yn millimeters (mm)
S - nominale muorre dikte fan fjouwerkante stielen piip, yn millimeters (mm)
