应用说明

This App has been designed by an Engineer, for an Engineer/Technician.

The Building Services Calculator currently includes a fully functional Metric Gas Sizer, Pipe Sizer, and a Duct Sizer. The App has been built around the formulas and procedures used within the CIBSE guides.

The Building Services Calculator was designed to provide professional accurate calculations, whilst also being informative, easy, and quick to use. The Gas Sizer, Pipe Sizer, and Duct Sizer feature a pre-set 'Simple' mode, or a custom 'Advanced' mode. The ‘Simple’ mode allows the user to select pre-set scientific data, materials, and sizes stored within the App whilst the ‘Advanced’ mode enables the user to enter their own custom inputs, whether that be a non-standard pipe size to a custom fluid density...

The Pipe Sizer (Pipeulator) features:

Select a liquid temperature from 5 to 100 degrees C for scientific data.
Select a pipe material from Copper, Steel, PVC-U, or ABS for scientific data.
Select flow units from either Kg/s or l/s.
Select a standard nominal pipe diameter (based upon the pipe material selected).
Inside diameter of nominal pipe size is displayed, or a custom inside diameter can be entered.
Liquid velocity is calculated and displayed.
Pressure drop is calculated and displayed.
Velocity pressure is calculated and displayed.
Liquid density is displayed (based upon the temperature selected), or a custom density can be entered.
Liquid dynamic viscosity is displayed (based upon the temperature selected), or a custom dynamic viscosity can be entered.
Kinematic viscosity is calculated and displayed.
Pipe material roughness is displayed (based upon the pipe material selected), or a custom material roughness can be entered.
Reynolds number is calculated and displayed.
Pipe fitting zeta factors can be entered. The fitting pressure drop is calculated and displayed.
The overall pressure drop including pipe length and fittings is calculated and displayed.

The Duct Sizer (Ductulator) features:

Select an air temperature from 0 to 40 degrees C for scientific data.
Select a duct type from either spiral or rectangular.
Select flow units from either Kg/s, l/s, or m3/s.
Select a standard duct diameter or a custom diameter can be entered.
If a rectangular duct size is entered the equivalent diameter (velocity) is calculated and displayed.
If a rectangular duct size is entered the equivalent diameter (pressure drop) is calculated and displayed.
Air velocity is calculated and displayed.
Pressure drop is calculated and displayed.
Velocity pressure is calculated and displayed.
Air density is displayed (based upon the temperature selected), or a custom density can be entered.
Liquid dynamic viscosity is displayed (based upon the temperature selected), or a custom dynamic viscosity can be entered.
Kinematic viscosity is calculated and displayed.
Pipe material roughness is displayed (based upon the duct type selected), or a custom material roughness can be entered.
Reynolds number is calculated and displayed.
Pipe fitting zeta factors can be entered. The fitting pressure drop is calculated and displayed.
The overall pressure drop including pipe length and fittings is calculated and displayed.

The Gas Sizer features:

Select a Gas Type from Natural Gas, Propane, or Butane for scientific data.
Select a pipe material from Copper, Steel, or PE for scientific data.
Enter a Heat Load or a Flow Rate, or convert between the two of them.
Gas velocity is calculated and displayed.
Total pressure drop is calculated and displayed.

Many new engineering calculations will be added to this App in the near future.
