* 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
*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 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
*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
*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
*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
*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
* 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
*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
* 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
*Can be fallible and can lead to wrong assumption and mislead action
* It’s math
*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)
*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!!!!
*Fuel Ratio =
*FIXED CARBON/VOLATILE MATTER*WOOOOOO
*OUTPUT/INPUT…… x100 !!!!!!
*In terms of Joules!
*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)
*To calculate geothermal energy you use:
*E=(3mt)^2*m= mass
*t=temperatureEasy
*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
*The Formula Is:
*Power= .5 x Swept Area x Air Density x Velocity^3
