A) 0.4
B) 0.6
C) 0.66
D) 1.66
Correct Answer: A
Solution :
\[{{R}_{d}}=\frac{{{(\Delta h)}_{m}}}{{{(\Delta h)}_{m}}{{(\Delta h)}_{f}}}=\frac{\frac{2}{3}{{(\Delta h)}_{f}}}{\frac{2}{3}{{(\Delta h)}_{f}}+{{(\Delta h)}_{f}}}\] \[=\frac{\frac{2}{3}}{\frac{2}{3}+1}=\frac{2}{5}=0.4\]You need to login to perform this action.
