Consider two identical buildings: one in Los Angeles, California, where the atmospheric pressure is 101 kPa and the other in Denver, Colorado, where the atmospheric pressure is 83 kPa. Both buildings are maintained at 21°C, and the infiltration rate for both buildings is 1.2 air changes per hour (ACH). That is, the entire air in the building is replaced completely by the outdoor air 1.2 times per hour on a day when the outdoor temperature at both locations is 10°C. Disregarding latent heat, determine the ratio of the heat losses by infiltration in the two cities.
Explain how hail forms? You need to understand that the middle part of a cumulonimbus cloud, where the air temperature is between -40° C and 0° C, there exists a combination of ice and supercooled liquid water droplets, which are cloud droplets that remain liquid even though the temperature is below the normal freezing point of liquid water. This should be part of your explanation. How large can hail get? Why are strong updrafts necessary to produce extremely large hail?
The wind-chill index is modeled by the function
W = 13.12 + 0.6215T – 11.37v0.16 + 0.3965TV0.16
where T is the temperature (°C) and v is the wind speed (km/h). When T = -19°C and v = 39 km/h, by how much would you expect the apparent temperature W to drop if the actual temperature decreases by 1°C? (Round your answers to two
decimal places.)

What if the wind speed increases by 1 km/h?

- You put two uncovered pails of water, one containing hot water and one containing cold water, outside in below-freezing weather. The pail with the hot water will usually begin to freeze first. Why? What would happen if you covered the pails?arrow_forwardIt is well known that wind makes the cold air feel much colder as a result of the wind chill effect that is due to the increase in the convection heat transfer coefficient with increasing air velocity. The wind chill effect is usually expressed in terms of the wind chill temperature (WCT), which is the apparent temperature felt by exposed skin. For outdoor air temperature of 0°C, for example, the wind chill temperature is 25°C at 20 km/h winds and -9°C at 60 km/h winds. That is, a person exposed to 0°C windy air at 20 km/h will feel as cold as a person exposed to -5°C calm air (air motion under 5 km/h).
