What is most nearly the room sensible heat ratio?Question 1 A) Considering the First-Law of thermodynamics, describe how we can reduce the temperature of a system? B) There are two different containers; the first one has hot water inside and the second one has cold oil. Can we have an identical thermal energy for these systems? Why?2- A conference room for seating 100 persons is to be maintained at 22 0C dry bulb temperature and 60% relative humidity. The outdoor conditions are 40 0C dry bulb temperature and 27 0C wet bulb temperature. The various loads in the auditorium are as follows: sensible and latent heat loads per person, 80 W and 50 W respectively; lights and fans, 15000 W; sensible heat gain through glass, walls, ceiling, 15000 W. The air infiltration is 20 m3 /min and fresh air supply is 100 m3 /min. two-third recirculated room air and one-third of fresh air are mixed before entering the cooling coil. The by-pass factor of the coil is 0.1 find 1-Apparatus dew point. 2-The grand total heat load. 3-Effective room sensible heat factor (ERSHF
- Distinction should be made between the surroundings, the immediate surroundings, and the environmentAnalyze the importance of thermodynamics knowledge to design a reaction or process system, from the viewpoint of Sustainable Development Goals, SDG 12: Responsible Consumption and Production.Integrated Concepts - (a) Suppose you start a workout on a Stairmaster, producing power at the same rate as climbing 116 stairs per minute. Assuming your mass is 76.0 kg and your efficiency is 20.0%, how long will it take for your body temperature to rise 1.00C if all other forms of heat transfer in and out of your body are balanced? (b) Is this consistent with your experience in getting warm while exercising?
- 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?step-by-step processWhy is information regarding the specific volume of gases important to the designer of air-conditioning, heating, and refrigeration equipment?
