Adding new material + unit conversion

[Asho Pulsar]

Hi guyz,


Whypro-e got its own material units for specific heat capacity and thermal conductivity?








The units for specific heat capacity and thermal conductivity shown in all the websites are J/kg/K and W/m K respectively. I need to add some material properties so i searched a lot in google, i cudnt able to get the unit conversion.


Doesanybody having any idea about the unit conversion for this particular thermal properties.

It's based on the system of units chosen and the values setup as the base units. Take a look at Info in the Units Manager. Since W=N*m/s, for the mmNs system W=N*mm/s (converting meters to millimeters) and converting temperature from Kelvin to celsius. When you cancel the units you get for thermal conductivity you get N/(sec C). For the mmKs system W is converted to W=(kg*mm^2)/(s^3*C) using N=kg*mm/s^2. Canceling units for thermal conductivity you get (mm kg)/(s^3 C).

So Kd2007,you mean to say, I can use the same value of Thermal conductivity and Specific heat capacity for a particular material in J/Kg/K and W/mKright...

Yes, the ProE units are simplified which is why they look the way they do. For your thermal conductivity, W/mK, your units are the MKS system. ProE uses W=(N*m)/sec. Simplifying the units you get N/(sec*K). When you set up the material select the N/(sec*K) and enter the value. If you needthe valuein a different system of units select the appropriate units and select convert value. You candetermine the units neededin the Units Manager by selecting info.

Yep Thanks a lot..
