The KELVIN PLANK statement may state as:

  • It is not possible to develop a device that can enable to operate in cycle and finally produce no effect rather than transferring heat from any cold reservoir to hot reservoir.
  • It does not allow creating a device that can operate in a cycle and finally have no effect other than increasing of weight and then transfer of heat with two reservoirs.
  • It is not possible to have a device that can operate in a cycle and finally have no effect rather than just increasing of weight and exchange of heat with single reservoir.

Kelvin Plank statement

Kelvin Plank statement says that it is not possible to create an engine that does not operate in cycle which can produce not any other effect apart from external heat from any single reservoir and that is equivalent to amount of work. This would consider any transform of heat into work.

You need to consider any reservoir that comes along with temperature T1 and the other reservoir at temperature T2. The temperature T1 appears to be higher than temperature T2. Look for heat pump that does not require any work and can transfer any amount of Q2 from any low temperature to high temperature reservoir.
