Assumptions & limits
Assumptions & limits
- Mass conversion using supplied densities/ratio and sprue allowance. No casting temperature, process safety, alloy recipe or yield certification. Supported limits: All numeric inputs must be finite. Only the explicitly described mathematical scenario is supported.
