A conditioned room with partial recirculation of room air is to be maintained at 24°C DB, 17°C WB. The local outside environment conditions are 35°C DB, 26°C WB. The sensible heat load is 48 kW. The latent heat load from occupants and infiltration, but excluding ventilation, is 57 kW. Based on the occupancy, 36 cmm of ventilation air is required. Find: (a) the temperature of air entering the room, (b) the volume of air passing through the room, (c) the state of air entering the conditioner, (d) the required ADP, and (e) the system BPF.

Basic Thermodynamics Question 422
The air in a theatre room must be 22 °C and the relative humidity 55%. The outdoor temperature is 30 °C and relative humidity 50%. There are 900 seats in the room and 25 m³/h of fresh air is reserved for each seat. Every attendant releases a heat load (sensible + latent) of 100 W and a moisture load of 80 g/h. The sum of heat loads from other than human sources is 20 kW. What must the supply air state be in order to maintain the indoor conditions mentioned above?

2) Two glass bulbs, one on the left with a volume of 2 liters and the other on the right with avolume of 6 liters, are connected to one another by a thin tube that is initially closed by astopcock. The bulb on the left has 0.1 moles of ideal gas, and the bulb on the right isevacuated. The system is in thermal equilibrium with the surroundings at 300K. When thestopcock is opened, the gas flows out to fill both bulbs. Calculate A for this process. If wewere to insert a propeller to extract work as the gas flows from left to right, what is themaximum amount of work that we could possibly extract?
