Paper format. 98-Phys-B6 Applied Thermodynamics and Heat Transfer, National Examination December 2013 — a three-hour open-book examination; candidates are expected to bring both a thermodynamics text and a heat-transfer text to make use of the property tables. A complete examination is five questions — either three from Part A (Thermodynamics, Q1–Q4) and two from Part B (Heat Transfer, Q5–Q8), or two from Part A and three from Part B — every question carrying equal value; all eight are solved below as a complete study set. Candidates are invited to state any assumptions where a question is open to interpretation; this licence is used explicitly in Question 1(b) (standard air properties, not printed directly) and Question 7 (a printed convective "rate" read as a heat-transfer coefficient with a temperature unit omitted in print — the same omission the paper shows in Question 6's specific-heat units).
Reference texts. Y. A. Çengel and M. A. Boles, Thermodynamics: An Engineering Approach, 8th ed. (ideal-gas processes, vapour power cycles, gas-turbine/Brayton cycles, vapour-compression refrigeration); F. P. Incropera and D. P. DeWitt, Fundamentals of Heat and Mass Transfer, 7th ed. (conduction, natural convection, lumped-capacitance transient conduction, radiation exchange between surfaces, heat-exchanger LMTD analysis).
