http://large.stanford.edu/courses/2011/ph241/omar1/ WebGenerating Heat Fission Fission produces energy and nuclear power plants use the fission reactions of U-236 to generate heat that then is converted to electricity. In a nuclear power plant, there is a chain reaction. Uranium-235 reacts with a neutron to generate uranium-236. This splits into fission products and also produces additional neutrons. how long are narrow boats

Sometimes it is important to determine the heat transfer rate per unit area, or heat flux, which has the symbol \( \dot{Q}'' \). Units for heat flux are Btu/hr-ft 2. The heat flux can be determined by dividing the heat transfer rate by the area through which the heat is being transferred. how long are ndc codes
