Component and insulation weights

For information about how to setup and make net weight calculations for any part of the HVAC model, refer to Weight and Center of Gravity (CofG).

Insulation weight

For information about how to apply and show insulation for components and elements, refer to Insulation Functionality.

The weight of the insulation material depends on the following HVAC duct shapes:

• Rectangular

• Oval

• Circular

Rectangular and oval components use the following formula to calculate insulation weight:

• Weight = Component weight + 2 * (Width + Height) * fitLen * insulationThickness * DENS

  Component weight	Component reference Cweight
  Width, Height	Cross-section values
  fitLen	Component length
  Insulation thickness	Thickness based on the selected insulation specification
  DENS	Material reference density

Circular components use the following formula to calculate insulation weight:

• Weight = Component weight + ((BORE * BORE) + (BORE * BORE) + (BORE * BORE)) * 3.1415926535897932 / (12.0 * TLEN * DENS)

  Component weight	Component reference Cweight
  BORE	Width (cross section) of the circular shape
  TLEN	Component length
  DENS	Material reference density

Tubes use the following formula to calculate insulation weight:

• WeightOfTube = Tube weight + BORE * BORE * 3.1415926535897932 * 0.25 * TLEN * DENS

  Tube weight	Component reference UWEI
  BORE	Width (cross section) of the circular shape
  TLEN	Tube length
  DENS	Material reference density
