Question One C (Basic Concepts) (6 points) Justify the following: a. b. C. The sun behaves like a black body On contrary to any other building material, glass is a selective material We use relative humidity (+)- not humidity ratio (W)- to indicate whether the air is dry or wet d. The radiosity of a black body is equal to its emissive power Question One D (First Law of Thermodynamics) (4 points) An AC split unit in a room conditions recirculated air (p=1.2 kg/m) and delivers it at a temperature of 12°C and volumetric flow rate of 0.5 m³/s. If the capacity of the system is 2 tons, what must be the minimum set-point temperature in the room so that the system is not overloaded? Specific heat of air (c₂) =1.006 kJ/(kg.K) Question One C (Basic Concepts) (6 points) Justify the following: a. b. C.
