A) 0.5279 and 0.550
B) 0577 and 0.550
C) 0.577 and 0.546
D) 0.5279 and 0.546
Correct Answer: C
Solution :
\[\frac{{{p}_{1}}}{{{p}_{2}}}={{\left( \frac{2}{n+1} \right)}^{\frac{n}{n-1}}},\] N = 1.135 for dry saturated steam sad 1.3 for superheated steam \[={{\left( \frac{2}{2.135} \right)}^{\frac{1.135}{0.135}}}=0.577={{\left( \frac{2}{2.3} \right)}^{\frac{1.3}{0.3}}}\]
