A T-type Copper/Constantan thermocouple (k = 25 W/mK, p = 8400 kg/m³, c = 0.4 kJ/kgK) can be modeled as a sphere. It is often used in extremely low temperature applications such as cryogenics or ultra-low freezers. In an experimental procedure, T-type Copper/Constantan thermocouple is wanted to use measuring the temperature in a CO2 stream in a square-cross sectioned duct with h=542,24 W/m?K. The duct cross-sections are 20mm*20 mm, and length is 500 mm. It is aimed that thermocouple measure the temperature difference as 95% with 8,55 s. What is the diameter [mm] of the thermocouple for this condition?

Problem- Cargo ships can cause a lot of air pollution.Solution- to use nuclear powered ships since they hold a lot of energy and can travel for long distances. How it will work is that it will need a nuclear reactor at the bottom of the boat to heat up the water and then turn it to electricity to power the boat. The boat will be made out of graphene which is a tough material to avoid any leaks in the boat. It will also contain many control rods because nuclear power is so powerful that it can create to much energy to handle. With control rods, you can slow down this process and keep it in a controlled manner. Since cargo ships are already is the ocean, there will be no need for any extra materials to make it work. -Do you think this will work? Why/Why not? -What do you think is wrong with it/ How can this be improved? Please send this to someone else I need to record 50 responses for a science project. Thank you!
