Participation reward: 2 Wealth. Reward for the correct answer: 9 Wealth. There is an air-conditioned room in which air is distributed using circular diffusers; based on isothermal jet calculations, the average wind speed inside the room is 0.25 m/s. What are the average wind speeds inside the room when cool air is supplied in summer and warm air is supplied in winter? A. 0.25m/s, 0.25m/s B. 0.25m/s, 0.2m/s C. 0.3m/s, 0.25m/s D. 0.3m/s, 0.2m/s
D.0.3m/s，0.2m/s
D.0.3m/s，0.2m/s
D.0.3m/s，0.2m/s
D.0.3m/s，0.2m/s
D.0.3m/s，0.2m/s
D.0.3m/s, 0.2m/s. In an air-conditioned room where air is supplied through circular diffusers, the average wind speed inside is calculated to be 0.25m/s using the isothermal jet method; therefore, the average wind speeds inside the room when cool air is supplied in summer and warm air is supplied in winter are (D.0.3m/s, 0.2m/s) respectively.
