Chapter 7, Problem 7.27CU

EXPLAIN THE THE DECREASE OF EXERGY PRINCIPLE AND EXERGY DESTRUCTION.

Thermodynamics, please help and show all work please. Part d.

I'm not sure how the values for the last two rows were found.

7.5 Equal molar amounts of carbon monoxide and neon are maintained at the same temperature and pressure. Which has the greater value for exergy relative to the same reference environment? Assume the ideal gas model with constant c, for each gas. There are no significant effects of motion and gravity.

Thermodynamic Keys Conservation of Mass Questions 71-75 are based on the stated information listed below. A feed water heater operating at steady state has two inlets and one exit. At inlet 1, liquid water at Pi = 7 bar, TI 40°C, vị = 1.0078x10 m/kg enters through an area of AI = 25 em. At inlet 2, water vapor enters at P2 =7 bar, T2 200°C, v=0.2999 m'/kg with a mass flow of 40 kg/sec. Saturated liquid exits at 3 at P, =7 bar, v= 1.108x10 m/kg with a volumetric flow rate of 0.06 m/sec. 71. The mass flow rate at the exit in kg/sec is a. 40.00 b. 14.15 c. 54.15 d. none of the above. 72. The mass flow rate at inlet 1 in kg/sec is 40.00 14.15 a. b. 54.15 c. d. none of the above. 73. The velocity at inlet 1 in m/sec is a. 16.1 b. 5.7 c. 21.8 d. none of the above. 74. The volumetric flow rate at inlet 2 in m/sec is 0.014 0.06 b. 12.00 a. с. d. none of the above. 75. The volumetric flow rate at inlet 1 in m³/sec is a. 0.014 b. 0.06 с. 12.00 d. none of the above.

At a pressure of 1 bar, a temperature of 17 °C and a mass flow of 0.3 kg/s, air enters a stable insulated compressor and exits at 3 bar, 147 °C. Determine the power required by the compressor and the exergy destruction in kW. Express the exergy disappearance as a percentage according to the power required by the compressor. Changes in kinetic and potential energy will be neglected. dead state; T0=17 °C, P0=1 bar

For the same initial and final states the change of entropy for constant .10 * volume process is greater than that for constant pressure process False True O According to the first law of thermodynamic the heat engine can.11 produce work less to the gross heat supplied False O True According to the second law of thermodynamic the heat engine can .12 * produce work equal to the gross heat supplied False O True

Topic: Ideal gas process Instructions: Answer the following review questions and show complete solutions. *please write legibly. Thank you

Carbon dioxide (CO2) at 1 bar, 300 K enters a compressor operating at steady state and is compressed adiabatically to an exit state of 10 bar, 580 K. The CO2 is modeled as an ideal gas, and kinetic and potential energy effects are negligible.For the compressor, determine:(c) the percent isentropic compressor efficiency.
