- 5. The following expressions relate to a particular gaseous mass: PV = 95T, h = 120 + 0.60T where these units obtain in lb/ft?, V = 500 ft /lb, T in •R and h in BTU/lb. If the specific heats are temperature dependent only, find Cp and Cv.arrow_forwardthermodynamics In order to describe the state of the water using the pure substance tables given below, 2 features are given. Determine the properties or properties asked from you for the following situations using thermodynamic tables and show the calculations.d. P = 1700 kPa T = 3000oC x =? h =? Phase state =?e.

- A piston/cylinder arrangement contains 2 kg of ammonia at a temperature 132.45 ℃ and a pressure 5 MPa. The piston floats. Heat is added to the system until the temperature of ammonia reaches 416.37 ℃. (a) Determine the phase of ammonia during the whole process (from the initial to the final state). [Hint : Use the tables in App. 5]. b) Show the initial and final points of the process in a T-s and p-v diagram. In both diagrams sketch the dome. Show these two points relative to the dome. (c) Determine the initial and final volume of the piston/cylinder arrangement using tables.

- The following thermodynamic potential functions H (enthalpy), A (Helmholtz function), G (Gibbs function) and U (internal energy) are connected by a system known as Maxwell's relations. Explain what is meant by Maxwell relations. If you know that dU = – P dV + T dS (P is pressure, V is volume, S is entropy and T is temperature), use the Legendre differential transformation to prove that dA = – P dV – S dT. In your own words, explain the role and importance of functions A and U.arrow_forwardThe pressure of the air in a starting air vessel is 40 bar and the temp is 24 deg C. If a fire in the vicinity causes the temperature to rise to 65 deg C, find the pressure of the air. Neglect any increase in volume of the vessel.arrow_forward(Q5] (a) The chamber contains 0.05 m' of ideal gas at a pressure of 20 KPa. The gas is subjected to an isothermal compression. until pressure reaches to 30 KPa. After that the gas is subjected to compression according to PV 2-const until pressure reaches to 40 KPa then an isobaric compression is done till volume reaches 0.005 m3. Assume that no loss in gas during the whole process : I- Sketch the process on P-V diagram and P-T diagram II- Find the work done during the entire process and temperature at end of each process.. gasarrow_forward
