Determine the heat-transfer rate per square meter of wall area for the case of a furnace with inside air at 1340 k. the furnace wall is composed of a 0.106-m layer of fireclay brick and a 0.635-cm thickness of mild steel on its outside surface. heat transfer coefficients on inside and outside wall surfaces are 5110 and 45 w/m2 ? k, respectively; outside air is at 295 k. what will be the temperatures at each surface and at the brick-steel interface?

conduction, convection, radiation

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
