Names (A How much energy did Hurricane Katrina extract from the Gulf of Mexico? B What information do we need Katrina to solve the problem? 1) A Law of Physics (Thermodynamics) (a) What is the Temperature change? Energy = (Specific heat x Mass x Temperature change) + (Vaporization heat , Mass (b) What is the mass of water that lost heat? 2) Properties of water: Volume [Length s widths height x Density = Mass 1060km Water Specific Heat of water = 4186 J/ (kg-k) Density of Sea Water = 1000bg/m (c) Energy extracted? (use our Law of Physics) Water Length Thickness Sea Surface Temperature (*F) Width 30 40 50 60 70 00 90 - - Kamena entered the Gull of Mexico on August 26, 2005, The U.S. uses approximately 1.0 x 10"J of energy each year (Total energy use, and made landlail near New Orleans on August 29, 2005, How does this compare to the energy budget of Hurricane Katrina? What was the average heat transfer each day? each hour? during its franall of the Gun
