  1. Energy Math! By: J.C. Cooper BijanRahimijimi Jake Rubendall

  2. 1)It is math applied to/used for… • …calculating • …measuring • …providing • …predicting • …(any other scientifically appropriate verb) • any and all things behind/resulting from/residing with the concept of energy. • 2) It’s not fun What is Energy Math, Might You Inquire?

  3. Regular Math Deals with random, arbitrary variables and concepts that have no direct impact or impression upon our lives except stress, boredom, and a compulsion to burn schoolwork and eat food i.e. Calculus Energy math isn’t just any math…

  4. Energy Math Energy math is literally the exact same thing as regular math, but uses 1. different variables, has 2. different applications, and works with 3. different concepts It is math, applied to energy You have a formula, and you plug values into variables to generate an answer i.e. Energy Density It works like this…

  5. Energy equals mass multiplied by the (speed of light) squared • Applies to kinetic, potential, chemical, thermal energy, the Doppler effect, nuclear energy and many other things Examples

  6. A formula to calculate the heat output of a solar panel • Note the different variables that require values to be inputted to generate a final value • Real life math-energy application More Examples

  7. Energy math is a way of computing and comprehending different measurements of energy • It is a practice that makes the natural phenomena of energy-use objective • Therefore it is best suited to be used by scientists, and can be applied anywhere Note: Energy Math is NOT a source of energy

  8. It is used to: • Estimate the volumes of oil and gas in reservoirs • Optimize performance across a broad spectrum of energies • Minimize costs and environmental impacts • Design many energy-related technologies (turbines, solar panels) • Create geothermal systems • It’s very real How realistic is this practice?

  9. The History of Energy Math The Future of Energy Math Applies to many contexts: mechanics, chemistry, biology, earth sciences, cosmology, energy and life As these sciences grow, so must the math that accompanies it Energy math will be with us until we decide to forget exactness and objectivity • Energy derived from the Greek word ‘energeia’ in the 4th Century BCE • Mathematical concept of energy derived from the idea of “vis viva” or living force • Defined by Gottfried Leibniz as the product of the mass of an object and its velocity squared Will we use energy math in the future?

  10. Advantages Disadvantages Can be fallible and can lead to wrong assumption and mislead action It’s math • Provides objective data for politicians and voters to make decisions off of • Can provide solutions for the future based off of past and contemporary consumption and management • Is an ever expanding tool • Applies to every area of energy • Tempers our destruction of the Earth Energy Math: Good or Bad?

  11. Aboveground biomass density (t/ha) = VOB * WD * BEF Where : WD= volume weighted average wood density (1 of oven-dry biomass per m^3 green volume) BEF= biomass expansion factor (ratio of aboveground oven-dry biomass of trees to oven-dry biomass of inventoried volume) How to calculate an increase in Biomass!

  12. To calculate the CO2 Emission Factor: • t/CO2/TJ= As receive carbon x 3.667 x [10,000/NCV(p)] in kJ/kg = As received Carbon x 3.667 x [2388.46/NCV(p)] in kcal/kg • YAY!!!! Calculate the CO2 Emission Factor!!

  13. Fuel Ratio = • FIXED CARBON/VOLATILE MATTER • WOOOOOO Calculate Fuel Ratio!!!

  14. OUTPUT/INPUT…… x100 !!!!!! • In terms of Joules! Calculate Energy Efficiency!!!!

  15. To find out how much you are paying for electricity you do this: • amps x volts = watts • 1000 watts/hour = kilo-watt hour (kWh) • 1 kilo-watt hour is how you are billed by the electric companies (all relative to the rate) How much you paying for electricity? Calculate IT!!!!

  16. To calculate geothermal energy you use: • E=(3mt)^2 • m= mass • t=temperature Easy Calculate Geothermal Energy!!!

  17. Here it is!! • Q= 3550k (h/I SG)^1/2 • Where: • Q= natural gas flow capacity (cfh) • h= pressure drop (in water column) • I= length of pipe (ft) • K = [d^5/(1+ 3.6/d +.003d)]^1/2 • D= inside diameter pipe (in) • SG = specific gravity Want to Calculate the capacity of a low pressure natural gas pipeline with a small pressure drop??

  18. The Formula Is: • Power= .5 x Swept Area x Air Density x Velocity^3 Calculate Wind Power!

  19. The End
