An air-standard dual cycle has a compression ratio of 9. At the beginning of compression, p1 = 100 kPa, T1 = 300 K, and V1 = 14 L. The total amount of energy added by heat transfer is 22.7 kJ. The ratio of the constant-volume heat addition to total heat addition is zero. Determine: (a) the temperatures at the end of each heat addition process, in K. (b) the net work per unit of mass of air, in kJ/kg. (c) the percent thermal efficiency. (d) the mean effective pressure, in kPa.

Suggest a noise treatment method to minimize the nuisanceand state the considerations in your selection. Plant rhabdoviruses infect a range of host plants and are transmitted by arthropod vectors. In regard to these viruses, answer the following questions:a. Plant rhabdoviruses are thought to have evolved from insect viruses. Briefly describe the basis for this hypothesis? c. Recently, reverse genetics systems have been developed for a number of plant rhabdoviruses to generate infectious clones. What are the main components and attributes of such a system? (3 marks Imagine that data collected in Ireland reveals that a 10% increase in income leads to the following changes: *A 21% increase in the quantity demanded of gourmet coffee "A 6% decrease in the quantity demanded of sliced bread A 9% increase in the quantity demanded of wine The income elasticity of demand for wine is . (Be careful to keep track of the direction of change. Like the cross price elasticity of demand, the sign of the income elasticity of demand can be positive or negative, and important information is conferred by the sign.) According to the income elasticity of demand, gourmet coffee is Which of the following three goods is most likely to be classified as a luxury good? O Sliced bread Gourmet coffee Wine good and sliced bread, 4 good.Previous question A 0.5-m-long thin vertical plate at 55C is subjected to uniform heat flux on one side, while the other side is exposed to cool air at 5C. Determine the heat transfer due to natural convection. \( x^{3} y^{\prime \prime \prime}-3 x y^{\prime}+80 y=0 \) is a Cauchy-Euler equation. True False A Moving to another question will save this response. 1 If you had a sample of 2400 radioactive atoms, how many ofthem should you expect to remain (be undecayed) after onehalf-life?2 If one half-life for your coin flips represents 36 years, whatamoun Consider the following equation: 3x+5=13(a) If x is equal to the number of trucks, is it possible to find an exact value for x? Use the language of abstract algebra to explain why or why not.(b) If x is equal to the number of kilograms gained or lost, is it possible to find an exact value for x? Use the language of abstract algebra to explain why or why not.

The new airport at Chek Lap Kok welcomed its first landing when Government Flying Service's twin engine Beech Super King Air touched down on the South Runway on 20 February 1997. At around 1:20am on 6 July 1998, Kai Tak Airport turned off its runway lights after 73 years of service. (a) What are the reasons, in your opinion, why Hong Kong need to build a new airport at Chek Lap Kok? An I-beam made of 4140 steel is heat treated to form tempered martensite. It is then welded to a 4140 steel plate and cooled rapidly back to room temperature. During use, the I-beam and the plate experience an impact load, but it is the weld which breaks. What happened? A mesh of 4-node pyramidic elements (i.e. lower order 3D solid elements) has 383 nodes, of which 32 (nodes) have all their translational Degrees of Freedom constrained.
