Hi David,
I am sorry that you are the only one I know from the code committee. Therefore I will shoot my question on you.
I was wondering if you can clarify the following:
The Table C-3 was introduced as the "Mean Coefficient of Linear Thermal Expansion Between 70 deg F and Indicated Temperature, min./in.-deg F". Is this really correct?
I can see that similar title is used for Table C-1, and I see that the linear expansion is zero at 70 deg F. So its title reflects what exactly it is.
The same does not look apply for the Table C-3. The coefficient is not zero for 70 deg F. I am guessing that the coefficients looks independent from 70 deg F, and the title is misleading or I am missing something. I would like to have your opinion on this.
Let us assume the table is correct, so how do you calculate the thermal expansion between 70 deg F and an arbitrary temperature?
Thanks in advance and kind regards,
