Is the specific heat at constant volume negative?
Thread Content
Colleagues, when I was performing calculations for the safety valve of the R507 refrigerant heat exchanger in accordance with GB150, it was necessary to determine the adiabatic index k. Since k equals the specific heat at constant pressure divided by the specific heat at constant volume, I used CoolPack to find the specific heat at constant volume under certain temperature and pressure conditions; however, the result was negative. I would like to ask everyone what is going on here? Have you encountered it before?
No, but it shouldn’t be a negative number, right?
I’ve really never encountered this before. Although it shows a negative value, I calculated it using the absolute value, but there’s still an issue with the result. I searched on Baidu, and it was said that it might be due to the negative value
