A) \[1.0207\,\,\text{kJ/kg}-K\]
B) \[1.869\,\,\text{kJ/kg}-K\]
C) \[1.891\,\,\text{kJ/kg}-K\]
D) \[0.9793\,\,\text{kJ/kg}-K\]
Correct Answer: A
Solution :
\[{{c}_{p}}\] of moist air \[=\,\,{{c}_{p}}\] of dry air + humidity Ratio \[\times \,\,{{c}_{p}}\] of water vapour \[=1.00+0.011\times 1.88\] \[=1.0207\,\,\text{kJ/kg}\text{.}\,\text{K}\]
