Air modeled as an ideal gas enters a turbine operating at steady state at 1040 K, 278 kPa and exits at 120 kPa. The mass flow rate is 5.5 kg/s, and the power developed is 800 kW. Stray heat transfer and kinetic and potential energy effects are negligible. Assuming k-1.4, determine (a) the temperature of the air at the turbine exit, in K. (b) the percent isentropic turbine efficiency.

In this discussion, you will briefly explain each of the four gas laws and apply an example as it happens in a refrigeration system. (Boyle’s, Charles’, Dalton’s, and the general law of perfect gases). In your contribution, also address the following: What makes matter change to different states? What type of energy do you think is the most important for the HVAC-R industry?
A 50 lb object is subjected to an applied upward force of 30 lbf. The only other force acting on the object is the force of gravity. The acceleration of gravity is 32.2 ft/s². Determine the weight of the object, in lbf, and the net acceleration of the object, in ft/s². Step 1 Your answer is correct. Determine the weight of the object, in lbf, with positive values being down. Ibf W = 50 Hint Step 2 * Your answer is incorrect. Determine the net acceleration of the object, in ft/s², with positive values being upward. i 12.88 ft/s² Attempts: 1 of 4 used

The 1st law of thermodynamics is ΔU = Q –W. Use this statement of the 1st law to show (mathematically) its equivalent statement: “Total energy of the universe is constant”. Here, the universe can be defined as: system + surroundings (everything but the system –everything outside the system). (Hint: this can be shown by two ways-you may either treat system and surroundings as two systems next to each other, or you may treat system + surroundings (universe) as one system.)
* Your answer is incorrect. A piston-cylinder assembly contains 0.7 lb of propane. The propane expands from an initial state where p₁ = 60 lbf/in.² and T₁ = 70°F to a final state where p₂ = 10 lbf/in.² During the process, the pressure and specific volume are related by pv² = constant. Determine the energy transfer by work, in Btu. W = i 3.123 Btu
Assume the following: ●In a light water reactor, approximately 1.0kg of spent nuclear fuel is produced for every50. megawatt-days (MWd) of thermal energy input. ●For the purposes of this analysis, assume the spent nuclear fuel produced is 1.8% Pu-240by mass. Pu-240 has a half-life of 6,430 years. ●The thermal efficiency of the power plant is 38% ●Use equation for radioactive decay: Qt= Q0^e-kt where: ○Qt = quantity of radioactive material at time t ○Q0 = original quantity of radioactive material ○k = the decay constant ○t = time interval in years ○The decay constant k is defined by the relation: Half life = ln(2)/k Diablo Canyon stores 95% of its spent nuclear fuel onsite. ii) How many metric tons of Pu-240 in the spent fuel will still be onsite in that year?
