ESStableD.ocx Data Error Rate Table

1. Error Rate Summary

2. Comparison Table

 

2.1 Saturated Water and Saturated Steam

 

2.2 Superheated Steam and Sub-cooled Water

The ESStableD.ocx data error table below has been prepared by one of our users in order to find the error rate of ESStableD.ocx in comparison with ASME steam tables.

Please note that ESStableD.ocx is based on MKS units while the ASME steam table used is British units.   Therefore, the error rates include the errors of unit conversion.
