You guys are doing a great job! Keep it up :D Also, had a small question in mind. Won't viscosity change if the temperature of the fluid changes? Will it help in better fuel utilization in the case of airplanes?
Nice Question! Viscosity does indeed change with a change in temperature. In fluids like water (liquids) an increase in temperature generally leads to a reduction in viscosity (think of the molecules moving away from each other), whereas in fluids like air (gases) viscosity is based on the collisions between particles and this increases with an increase in temperature. Your point about changing temperature to influence viscosity is indeed an intriguing question. One way to possibly change the viscosity of the air is to cool the wing and hope that heat conduction to the air is high enough to change a significant portion of the air's viscosity (since all around it fluid will still be at the temperature of that altitude). However the question to be asked is, even if we somehow manage to change the viscosity of air in contact with the wing, will the energy expended trying to cool the air be greater than the savings accrued by a reduction in drag. Interesting question indeed!
HI SCIENTISTS YOU ARE MAKING THE SUBJECT VERY INTERESTING KEEP IT GOING
Thank you very much :-)

Good.
Creative keep it up
You can use hindi language some time so we can understand more effective
Thanks to you both for feel me fluid me😚😚😚
