WebOct 2, 2024 · It means that the protective device that we will use must have a short circuit capacity of more than 20 KA. It will help the Over Current Protective device (OCPD) to safely interrupt this amount of fault current. This blog has just provided you a basic idea of how we will calculate the amount of short circuit current for a small power system. WebKa is the acid dissociation constant while Kpa is simply the negative logarithm of Ka. The dissociation constant for a strong acid can be as high as 10^7 while for a weak acid it …
WebJan 10, 2024 · The constants Ka and Kb are related as shown in Equation 3.4.10. The pKa and pKb for an acid and its conjugate base are related as shown in Equations 3.4.15 and 3.4.16. Use the relationships pK = −log K and K = 10 −pK (Equations 3.4.11 and 3.4.13) to convert between Ka and pKa or Kb and pKb. WebJun 19, 2024 · Calculating K a and K b.
