Irreversible process work done

WebSelf-organization. Order and disorder. Category. v. t. e. In thermodynamics, a reversible process is a process, involving a system and its surroundings, whose direction can be reversed by infinitesimal changes in some properties of the surroundings, such as pressure or temperature. [1] [2] [3] Throughout an entire reversible process, the system ... WebNov 15, 2012 · The irreversibility of the process does not change the definition of work. Pressure is normal force divided by area. "Normal" refers to the direction of the force, not the type of force. The force can be dissipative. For instance, one can have a normal force that includes a component of friction.

[Solved] Work done by reversible and irreversible process

WebAnswer: No. Workdone in reversible is always more than the workdone in irreversible. The reason is the system has to work against the gradual higher external pressure in reversible condition. Whereas the external pressure is constant, no rising in irreversible condition, hence work is less.
