In transient heat transfer, the rate of heat transfer is changing with time. By definition, in steady-state heat transfer, the rate of heat transfer does NOT change with time. In the real world, heat transfer starts out as transient and then approaches steady-state with time until the difference between the actual and the ideal becomes negligible or until thermal equilibrium is approached.

What is transient heat transfer?
Transient heat transfer refers to the heat transfer process that occurs over a time period during which the temperature distribution within a system changes with time. This is in contrast to steady-state heat transfer, where the temperature distribution remains constant with time. Transient heat transfer is commonly seen during processes such as heating or cooling of materials, where the temperature changes over time.
What is unsteady state condition in heat transfer?
Unsteady state condition in heat transfer refers to a situation where temperature distribution within a system changes over time. This means that the system does not reach a steady state where temperatures remain constant. Unsteady state heat transfer occurs during transient processes such as heating up or cooling down a system.
What is the difference between steady state and unsteady conduction?
In steady-state conduction, temperature and heat transfer remain constant with time, while in unsteady conduction, temperature and heat transfer change with time. Steady state occurs when the temperature distribution does not change over time, whereas unsteady state occurs when there is a time-dependent temperature distribution.
What is mean transient stability?
Mean transient stability is referring to a synchronous power system's ability to overcome a large disturbance. The transient stability represents the synchronous power system stabilizing and maintain it's synchronous balance.
Why is it necessary to obtain steady state before observation?
Sort of depends on what you're observing (watching a rocket go into orbit would be a fine example where waiting for "steady state" would be silly) but in many cases the results are false (or weird) until things quiet down.

What is meaning for transient in RLC series circuit?
In circuit analysis, there is steady state and transient conditions. transient conditions are how the circuit acts immediately following some action (such as turning on power, closing a switch, losing power, etc.). Steady state conditions is everything else.
What are transient and steady state conditions in Markov Chains?
Please consult some book.
What is environment to you?
Environment is the set of physical conditions surrounding a given object. It can be steady-state or transient.
What is unsteady state condition in heat transfer?
Unsteady state condition in heat transfer refers to a situation where temperature distribution within a system changes over time. This means that the system does not reach a steady state where temperatures remain constant. Unsteady state heat transfer occurs during transient processes such as heating up or cooling down a system.
What is transient voltage?
A transient voltage is a time varying voltage value. Transient says that the voltage value changes, especially from a steady state, to a new value, then back again.
Steady state gain of the system?
The steady state gain of a system is the ratio of the output to the input when the system has reached a constant output value for a constant input signal. It indicates how the system responds to a steady-state input, regardless of transient behavior. Mathematically, it is calculated as the ratio of the output to the input when the system has reached steady state.
What component limits current in a circuit?
A resistor or an inductor. The inductor limits transient current, not steady state current.
Difference between steady state and transient analysis?
In steady state analysis, you assume anything that changes with time is 0. ie: d*rho/dt = 0. In transient, you keep all your d/dt terms. Steady state simplification is a handy tool to make many differential equations solvable, by reducing their "dimension", as x-direction, y-direction, z-direction, and time are each dimensions.
What Is transient time?
Transient time refers to the period it takes for a system to reach a stable state after a change or disturbance. It is the time it takes for a system to settle down and for its outputs to stabilize after a varying input. In electrical engineering, transient time can refer to the time it takes for a signal to reach a steady state after a change in inputs or conditions.
What is the difference between steady state and unsteady conduction?
In steady-state conduction, temperature and heat transfer remain constant with time, while in unsteady conduction, temperature and heat transfer change with time. Steady state occurs when the temperature distribution does not change over time, whereas unsteady state occurs when there is a time-dependent temperature distribution.
Why steady state heat transfer doesnot change with respect to time?
Steady-state heat transfer does not change with time - because - that is the definition of steady-state, i.e. "steady-state" means "does not change with time".As for why heat transfer might be steady state - that would be a consequence of the driving forces and physical conditions remaining constant with time. For example:Heat source remains the same temperatureHeat sink remains the same temperatureHeat source remain in the same position relative to each other, both in terms of distance and orientation.Surface areas of heat source and heat sink remain the same.Any intervening medium remains the same composition, temperature, density, and pressure.If convection is occurring, flow rates remain constant.If radiative heat transfer is occurring, any intervening medium has constant transmissivity, reflectivity, and absorbtion.If radiative heat transfer is occurring, radiating and absorbing surfaces maintain constant radiative and absorbing properties.There are a few other factors that can influence steady-state heat transfer, but these are a good description of the most important ones.
