If the specific heats of a gas and a vapor are 0.2KJ/Kg.°K and 1.5 KJ/Kg.°K respectively, and the humidity is 0.01; the humid heat in KJ/°Kg. is________________?
Correct answer: D. 0.215
- A. 0.31
- B. 0.107
- C. 0.017
- D. 0.215
Explanation
Humid heat is the heat capacity of dry gas plus the vapour contribution: c_H = c_g + Hc_v = 0.2 + (0.01)(1.5) = 0.215 kJ/(kg dry gas·K).
