Respected sir, At 6:35 time it is told that density is directly proportional to pressure. This is true when the temperature is constant. Otherwise, density will vary with temperature also. In this case, the temperature is not constant. So, from that point of view is it possible to conclude that this is also a case of pressure-driven flow? Thank you in advance
1) Negligibly pressure driven but significantly temperature driven flow..... 2) Practically pressure gradients exists only within the domain of heat transfer & bulk diffusion.....still they can be neglected..... 3) Usually natural convection processes occurs at around atmospheric pressure...... 4) Here, the effect of pressure driven is like that it inherently present without external imposition..... & sir explained the same.....
