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.

Question

Air enters a compressor operating at steady-state at 1 atm with a specific enthalpy of
h1 = 224 kJ/kg and exits at a higher pressure with a specific enthalpy of h2 = 693
kJ/kg. The mass flowrate through the compressor is 0.1 kg/s. If the compressor input
power is measured to be 92 kW, determine the rate of heat transfer associated with
the process (kW). Kinetic and potential energy changes are negligible. (Note: be sure
to use proper sign convention for your answer.)

A gas with specific volume v₁ = 1 m³/Kg and pressure p₁=1bar in a closed system undergoes a thermodynamic cycle which consists of the following three separate processes: 1->2: Isobaric compression to v₂-0.25 m³/Kg 2->3: Isometric heating. 3->1: Isothermal expansion (pV = constant) to the initial volume. Calculate the specific work produced by the gas per cycle. Present your answer in kJ/kg.
Refrigerant 134a at p1 = 30 lbş/in?, T1 = 40°F enters a compressor operating at steady state with a mass flow rate of 250 lb/h and exits as saturated vapor at p2 = 160 lbę/in?. Heat transfer occurs from the compressor to its surroundings, which are at To = 40°F. Changes in kinetic and potential energy can be ignored. The power input to the compressor is 2.5 hp. Determine the heat transfer rate for the compressor, in Btu/hr, and the entropy production rate for the compressor, in Btu/hr-°R.
Five kilograms of a two-phase liquid-vapor mixture of water initially at 300\deg C and x1 = 0.5 is heated from the initial state to a saturated vapor state while the volume remains constant. The process is brought about by heat transfer from a thermal reservoir at 380\deg C. The temperature of the water at the location where the heat transfer occurs is 380\deg C.Let To = 300 K, Po = 1 bar, and ignore the effects of motion and gravity.
Thermodynamics A Piston-Cylinder system initially contains R-134a refrigerant at a temperature of 2.8 bar and 40 C, and its initial volume is 0.1 m3. First, heat is transferred to the system by keeping the piston constant and this process is continued until the pressure is 3.2 bar. the process is maintained by allowing the volume to change. At the end of this process, the temperature reaches 50C. Assuming the state changes as if balanced, calculate the following: a)He amount of heat transferred during constant pressure operation b)Show the state changes on the P-v diagram.
