Getting satellites into orbit is hard enough - they need to be hurled into space with enough energy to reach around 26,000km/h. But staying in orbit means avoiding losing energy to the Earth's atmospheric drag. While the official threshold of space is 100km above the Earth, the effects of the atmosphere can be detected much higher.
Aug 9, 2012 · The boundaries of survival are better established for long-term comfort. According to a 1958 NASA report, people can live indefinitely in environments that range between roughly 40 degrees F and ...
Nov 29, 2023 · For example, at high T air and low RH, young and healthy adults can do ~2.5–3.0 METs more activity (e.g., sitting/resting versus walking) than older adults, who are more limited by their sweat ...
Jul 10, 2021 · The conditions that can lead to a wet-bulb temperature of 95 °F vary greatly. With no wind and sunny skies, an area with 50% humidity will hit an unlivable wet-bulb temperature at around 109 °F ...
Jun 9, 2021 · The walking parameters were closely related to environmental temperature, with cadence most strongly correlated with daily maximum temperature (r = − 0.812, p < 0.001) and indicating a ...
Jun 6, 2018 · Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances. This is why water is valuable to industries and in your car's radiator as a coolant.
Aug 14, 2024 · WBT is a measure that scientists use when studying heat stress because it accounts for the effects of heat and humidity. The models churned out a WBT of 35 °C as the limit of human survival. At ...
