What is the physical meaning of the von Kármán constant?

Asked by: Anthony Carrick What is the value of Karman constant? The best estimate for the von Kármán constant in turbulent pipe flow is found to be 0.40±0.02. What is von Karman equation? The Von Karman equation introduced a system of two fourth order elliptic nonlinear partial differential equations which can be used to describe

When a tectonic plate subducts, does any of the subducted material melt, or is it just the mantle above the subducted slab that melts?

Asked by: Maria Molina What happens to a subducting plate after it Subducts? Once initiated, stable subduction is driven mostly by the negative buoyancy of the dense subducting lithosphere. The slab sinks into the mantle largely under its weight. Earthquakes are common along the subduction zone, and fluids released by the subducting plate trigger volcanism

What happens if it rains above the boiling point of water?

Asked by: Maria Molina It will depend on how the temperature and humidity change as the raindrops approach the bottom of the column. If the air is hothot‘Warm’ is used to explain the temperature below average. but ‘hot’ describes the temperature of objects especially in heat condition. Why is the boiling point lower when it

The seriousness of global warming/ climate change?

Asked by: Melissa Suddarth Earth Will Continue to Warm and the Effects Will Be Profound The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions, and an increase in the duration and intensity of tropical storms. How does global warming affect climate change? As the earth’s

Could the recent temperature anomalies in the arctic be used as a proxy measure of global heating?

Asked by: Melissa Suddarth Why are temperature anomalies typically used in global temperature calculations? Anomalies more accurately describe climate variability over larger areas than absolute temperatures do, and they give a frame of reference that allows more meaningful comparisons between locations and more accurate calculations of temperature trends. What happens when temperature anomaly occurs? A

How different can microclimates be than their surrounding areas?

Asked by: Ryan Doshi What might cause one microclimate to differ from another? Microclimates are caused by local differences in the amount of heat or water received or trapped near the surface. A microclimate may differ from its surroundings by receiving more energy, so it is a little warmer than its surroundings. Why do urban
