Hello friend...
I have confusion in understanding the concept of viscosity. Please help me.
Viscosity is the property of the fluid which offers resistance to the movement of one layer of fluid over another adjacent layer of the fluid. Here both top and adjacent layer causes shear stress on each...
Thanks Chestermiller and boneh3ad...
OK.
That means for constant wall temperature, wall is held at constant temperature and its heat flux (Heat transfer rate) may change.
But I am slightly confused for constant wall heat flux (For e.g. Hot fluid flows through pipe):Let us consider eqn. q= h x...
