Question: (c) On the psychrometric chart provided (Appendix 2), find the state point of an air stream with a dry bulb temperature of 27C and 80%

(c) On the psychrometric chart provided (Appendix 2), find the state point of an air stream with a dry bulb temperature of 27C and 80% relative humidity. Determine: (i) the specific enthalpy, moisture content and specific volume; (ii) the rate of thermal energy required to heat 15m3s4 of this air stream sensibly from 27C and 80% relative humidity to 35C. (d) If the above air (part c) at 35C is passed over a free water surface which is at 28C, estimate the rate of evaporation for each square meter of water surface. that is fequired to saturate the air stream, given that the mass-transfer coetficient is 0.015kgm1s1
