Calculations Flashcards
1
Q
Levelized cost of electricity: (Lc)
A
= fuel cost/efficiency +
+ investment cost/(load*load factor) *
* CRF
Capital recovery factor:
CRF = r/(1-(1+r)^-yr)
r = discount rate
2
Q
Price elasticity:
A
Q1 = Q0 (P1/P0)^eb P1 = P0 ( Q1/Q0)^(1/eb)
3
Q
Capital recovery factor:
A
CRF = r/(1-(1+r)^-yr) r = discount rate
4
Q
Discount rate/year (compare cars):
Expenses now vs. in the future
A
Investment cost +
+ fuel cost *
* ( (1/(1+r)^y1) + (1/(1+r)^y2) etc)
r = discount rate/year
5
Q
eV to J:
A
1 eV = 1.6 * 10^-19 J
6
Q
Prefix: (memorized)
A
Min Galna Trip På Extecy
7
Q
Avogadros number:
A
6*10^23 (atoms/mole)
