3. Air occupies a 0.3 m³ piston-cylinder at 150 kPa and 278 K. The piston-cylinder operates on a three-process cycle where from state 1 to state 2 the pressure constant and V2 = 1.4 V1. From state 2 to 3 the compression is reversible adiabatic until V3 = V1, and the temperature at state 3 is 450 K. A constant-volume process completes the cycle. Sketch the cycle on a p-V diagram and determine the network and heat flows for the cycle.

stream? Q2/ An ideal gas initially at 600 K and 10 bar undergoes a four step mechanically reversible cycle in a closed system. In step 1-2, pressure decreases isothermally to 3 bar; in step 2-3, pressure decreases at constant volume to 2 bar; in step 3-4, volume decreases at constant pressure; and in step 4-1, the gas returns adiabatically to its initial state.

A power plant operates in an idealized Rankine cycle, using water as the working fluid (Figure 3). The steam at the exit of the boiler has a pressure of 6 MPa and temperature of 600 °C (point 1). The water at the exit of the condenser has a pressure of 15 kPa (point 3). The condenser employs a nearby river as the cooling source, which can be regarded to have a constant temperature of 25 °C. The mass flow rate of the steam is 80 kg/s. The hot reservoir has a temperature of 1400 K. Regard water as an incompressible liquid.
