Imagine that today is your first day on the job, and that from now on you will be the engineer responsible for a thermal machine. The machine operates according to the cycle below, functioning as a Rankine cycle. Figure 1. T-S diagram of the Rankine cycle. As a good engineer, you already know that, in order to know how a machine works, it is necessary to know its operating conditions. The boiler operates at a constant pressure equal to 8600 kPa and generates water vapor whose temperature is 400 °C. When passing through the turbine, the steam is expanded isetropically and enters the condenser as a two-phase mixture with a title equal to 0.80. The fluid is condensed at a constant pressure of 10 kPa, and then compressed isentropically, so that the fluid enters the boiler as a subcooled liquid. According to the information given above, determine: a) The change in internal energy (ΔU) and the change in entropy (ΔS) of the cycle. b) The net work recognized by the cycle (WNet). c) The thermal…
