Steady state gain,

what is steady state flow process in fluid dynamics

Steady state temperature in an annulus of inner radius R1 and outer radius R2.Find the expression of the steady state distribution of the temperature T(x,y) satisfying the Laplace equation with the boundary conditions f(θ)

and g(θ) respectively on the circles with radii R1 and R2.

Question Modified:

this is the complete question.

steady state is a condition when the temperature neither increases nor decreases.....

The steady-state theory is obsolete - it is now known that the Universe does change over time (the Steady-State Theory states that it doesn't).

According to the Steady-State Theory, the Universe has no beginning and no end.
