Exhaust gases from a wire processing oven are discharged into a tall stack, and the gas and stack surface temperatures at the outlet of the stack must be estimated. knowledge of the outlet gas temperature 푇",$is useful for predicting the dispersion of effluents in the thermal plume, while knowledge of the outlet stack surface temperature 푇j,$indicates whether condensation of the gas products will occur. the thin-walled cylindrical stack is 0.5m in diameter and 6.0 m high. the exhaust gas flow rate is 0.5 kg/s and the inlet temperature is 600°c. a)consider conditions for which the ambient air temperature and wind velocity are 4°c and 5 m/s respectively. approximating the thermophysical properties of thegas as those of atmospheric air, estimate the outlet gas and stack surface temperatures for the given conditions.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
