How long does steady state take to attain? What conditions determine steady state? What methods could be employed to attain steady state faster? Graph A For the above graph it takes approximately 8 minutes for steady state to occur. The conditions that determine steady state are when heat transfer between the surface of the cylinder and the heating coil no longer occur and the temperature of the cylinder remains within one degree C for an extended period of time.
