Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

Air is compressed steadily by a reversible compressor from an inlet state of 100 kPa and 300 K to an exit pressure of 900 kPa. Determine the compressor work per unit mass for ideal two-stage compression with intercooling with a polytropic exponent of 1.3.
1. Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4 MPa, 500°C, and 80 m/s, and the exit conditions are 30 kPa, 92% quality, and 50 m/s. The mass flow rate of the steam is 12 kg/s. Develop the mass and energy balance for this situation. Then, determine (a) the change in kinetic energy, (b) the power output, and (c) the turbine inlet area. Provide all evidence (referred tables, equations used, etc.) to support your answers. P = 4 MPa T = 500°C V = 80 m/s Steam m = 12 kg/s W out P2 = 30 kPa X2 = 0.92 V2= 50 m/s
Water steam flows steadily through an adiabatic turbine. The inlet conditions of steam are 1.0 x 106 Pa and 600°C, one of the exit conditions is 7.5 x 10³ Pa. Assuming the process is isentropic, determine (with the help of the steam table): (a) the temperature of the steam at the exit (K). (b) the quality of the steam at the exit (%). (c) the specific enthalpy of the steam at the exit (kJ/kg). (d) the work done per unit mass by the turbine (kJ/kg).
