| Abstract: | In order to meet the experimental teaching requirements of the Engineering Thermodynamics course in the university, a new experimental system for measuring specific heat capacity of gas at constant pressure is designed and developed to solve the problem of inaccurate experimental results caused by the large range of heating temperature difference in traditional experimental devices. The new experimental system for measuring specific heat capacity of gas at constant pressure is designed by combining preheating section, heat preservation and two measurement algorithm improvements, which makes the experimental results more accurate and reliable. It truly reflects the experimental principle and has high accuracy, and fully meets the requirements of undergraduate research experiment teaching. |
