Heat Transfer
In which of the following process, convection does not takes place primarily?
The correct statement of the following: A) Water can be boiled inside the artificial satellite by convection B) Heavy liquid can be boiled in artificial satellite by convection Mark correct option/s
Conduction and Convection are non-existent in space, so both the statements are wrong.
In which of the following process, convection does not takes place primarily?
A double-plane window consist of two glass sheets each of area $$1m^2$$ and thickness $$0.01m$$ separated by a $$0.05m$$ thick stagnant air space In the steady state, the room glass interface and the glass outdoor interface are at constant temperature of $$27^oC$$ and $$0^oC$$ respectively. The rate of heat flow through the window plane is (Given , $$k_{glass}=0.8\,\,W\,\,m^{-1}K^{-1},K_{air}=0.08\,\,W\,\,m^{-1}K^{-1})$$
Why are chimneys provided over furnace in factories?
State whether the given statement is True or False. Most of the heat transfer that is taking place on the earth is by Radiation.
It is hotter at the same distance over the top of a fire than it is on the side of it mainly because
It is hotter at some distance over the flames than in front of it because :
While measuring the thermal conductivity of liquids, the upper part is kept hot and lower one cool so that :
Which of the following process does not occur through convection:
