You are asked to assist in the thermal design of a cryogenic system. The system component you are working on is required to thermally equilibrate as quickly as possible with the liquid nitrogen coolant being flowed through it. In other words, this component must cool from room temperature to liquid nitrogen temperature as quickly as possible. Of the four materials listed below, which would you choose based on this requirement? Material A Thermal Conductivity =12W/mK Heat Capacity: 4J/m3K Material B Thermal Conductivity =15W/mK Heat Capacity: 5J/m3K Material C Thermal Conductivity =8W/mK Heat Capacity: 2J/m3K Material D Thermal Conductivity =15W/mK Heat Capacity: 3J/m3K Material D Material B Material A Materials A and B will have equally good performance. Material C
