Simple thermodynamic problems
WebbLet us assume the Rankine cycle, one of the most common thermodynamic cycles in thermal power plants. In this case, assume a simple cycle without reheat and condensing steam turbine running on saturated steam (dry steam). In this case, the turbine operates at a steady state with inlet conditions of 6 MPa, t = 275.6°C, x = 1 (point 3). WebbThe first law of thermodynamics states that the change in internal energy of a closed system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is. Δ U = Q − W. 12.6. Here, Δ U is the change in internal energy, U, of the system.
