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.)
Explain the concept of system reliability and its significance in engineering applications.

PLEASE ANSWER ALL) An unknown ideal gas (MW=10 kg/kmol and k=1.3) closed system underwent in a cycle described by the following processes below:Process 1-2 : From 40°C and 1 bar to 3 bars isentropicallyProcess 2-3: Polytropically to 5 bars at n=2Process 3-1: Isometrically Find the pressure at the 3rd state in bars and overall change of entropy for the cycle in kJ/kg-K.
* 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

Q True or False 1. PMM1 states that: there can be no machine which would continuously supply mechanical work without some form of energy disappearing simultaneously. 2. The filling of a tank is an example of unsteady flow process. 3. For steam nozzle the change in potential energy is zero 4. In case of boiler the change in kinetic energy is zero. 5. For steady flow only interaction between system surroundings are work and heat. 6. Superheated steam behaves like a gas and therefore, it follows gas laws 7. Extensive properties do not depend on the mass of the system. 8. The change of internal energy for an isolated system is equal to heat and work. 9. With the use of centrifugal pump, the heat transfer is maximum. 10. For the flow in reciprocating compressor, the change in the kinetic energy is maximum
QUESTION 51 The following processes occurs in a reversible thermodynamic cycle: 1-2: Reversible polytropic compression at pressure 0.6 bar at volume 0.09 m to a pressure 11.1 bar and specific volume 0.3 m/kg. The index of compression may be taken as n. 2-3: Reversibly expansion with expansion index of 2 to pressure 1.6 bar. 3-1: Reversible cooling at constant volume to the initial state. Calculate the work for the compression in the process to 2 decimal places. Not in kilo or mega.
When you add heat to a system, by how much does its temperature change?
Thermodynamics
Some unknown gas undergoes a polytropic process, pV^1.5 = constant, the initial pressure, p1, is 1 bar, and the initialvolume, V1, is 1 m3. We also know the final volume, V2, is 4 m3. Please determine 1) the final pressure of the gas, p2, inbar; and the total work done by the gas, W, in kJ; 2) judge the direction of energy flow for the work: into the system or outof the system.
