| Abstract: | Without any change of other conditions,the rate of water flow will affect determination the value of the thermal conductivity of metal with the method of fluid heat transfer. Through lots of experiments and analysis of the results,the author has got a suitable rate of water flow, which will be significant to classroom-teaching instruction as well as the relavent study of the subject. |
