A gas turbine power plant operating on a Brayton cycle takes in atmospheric air at 16°C. The temperature of the air rises by 218°C over the compressor, and by a further 729°C over the combustion chamber. If the heating value of the fuel burned in the turbine is 40 MJ/kg, calculate the rate in kg/s at which fuel must be burned for each MW of output from the power plant. Give your answer to three decimal places. Take the specific heat capacity c, of air to be 1.005 kJ/(kg K), and the ratio of specific heats k to be 1.4. You may also assume that changes in the properties of the air due to the addition and combustion of fuel are negligible.

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!
