A) \[80{}^\circ C\]
B) \[444{}^\circ C\]
C) \[333{}^\circ C\]
D) \[171{}^\circ C\]
Correct Answer: D
Solution :
For open vessel p is constant, from Charles law \[I={{I}_{1}}\cos \,\omega t+{{I}_{2}}\sin \omega t\] \[\frac{1}{\sqrt{2}}({{I}_{1}}+{{I}_{2}})\] ie, \[\frac{1}{\sqrt{2}}{{({{I}_{1}}+{{I}_{2}})}^{2}}\] or \[\frac{1}{\sqrt{2}}{{(I_{1}^{2}+I_{2}^{2})}^{1/2}}\] \[\frac{1}{2}{{(I_{1}^{2}+I_{2}^{2})}^{1/2}}\] \[f\] or \[f\] \[f\] \[f<{{f}_{r}}\] \[f={{f}_{r}}\] or \[f>{{f}_{r}}\]
