Thirty pounds of ice at 32OF is placed in 100 lbs of water at 100 O The latent heat of ice may be taken as 144 BTU per lb. If no heat is lost or added to the mixture, the temperature (in Farhenheit) when equilibrium is reached is: a. None of these b. 51                      c. 48                       d. 49                      e. 50

Use the data from this table of thermodynamic properties to calculate the values of AS for each of the reactions at 25 °C. C(s, graphite) + H, O(g) CO(g)+ H,(g) AS = N, (g) + 3 H, (g) - 2 NH,(g) AS = K Question Source. McQuar

3.26 Determine the quality (if saturated) or temperature substances at the given two states: a. Water at b. Nitrogen at c. Ammonia at d. R-22 at 1: 120°C, 1 m³/kg; 1: 1 MPa, 0.03 m³/kg; 1: 400 kPa, 0.327 m³/kg; 1: 130 kPa, 0.1 m³/kg; (if superheated) of the following 2: 10 MPa, 0.01 m³/kg 2: 100 K, 0.03 m³/kg 2: 1000 kPa, 0.1 m³/kg 2: 150 kPa, 0.17 m³/kg

2. An ideal gas (the weight is m kg) in an idealized piston-cylinder assembly undergoes a series of processes from state 1 to states 2, 3 and 4. Each state is at equilibrium. The gas can be modeled as a closed system. Ignore changes of KE and PE. The states are fixed by the following properties in the table: State 1 2 3 4 8 7 9 Note: State 1 to 2 is a constant-temperature process. State 2-3 is a constant-volume process. State 3-4 is a constant-temperature process. (a) Mark the states 1-4 and draw the three processes (1-2, 2-3, 3-4) on the following p-v diagram. p (bar) 4 5 3 1 2 0 p (bar) 1 3 1 6 3 v (m³/kg) 3 1 1 2 2 300K 600K T (K) 300 300 600 600 3 4 5 v (m³/kg) 6 7 8 (b) Use equations and simple texts to explain and answer the questions for the two processes (process 1-2, and process 2-3), respectively. (i) How does the internal energy change during each process: no change, increase or decrease (AU)? (ii) How does the enthalpy change during each process (AH)? (iii) Is the work…

Question 13! This is applied thermodynamics! Please make sure work is written NEATLY and the answer is in the right units! Thank you!

Consider a tank containing gaseous Helium. It is perfectly insulated and rigid. There is a paddle wheel to stir the Helium, which is rated at 0.12. The paddle wheel is operated for 42 min. Determine the final equilibrium pressure of the He gas, in units of psia. The initial gas conditions are given in the table below: mass (Ibm) T (°F) p (psia) |1.3 68.1 43.5
