Paper format. National Examinations, May 2016 — 07-Mec-B3 Energy Conversion and Power Generation. Three hours, closed book. The paper has two sections: Section A (calculative) carries Questions 1 to 4 and Section B (descriptive) carries Questions 5 and 6. A candidate answers three questions from Section A and one from Section B, so four questions constitute a complete paper of 60 marks and every question is worth 15 marks. Reference data for particular questions are bound in as pages 9 to 12 (the Van der Kloof waterway cross-section, the Mollier enthalpy-entropy diagram, the Belledune Generating Station heat balance diagram and the coal fired boiler outline), reference formulae and constants as pages 13 to 16, and steam tables from Granet and Bluestein are supplied. All six questions are solved here, because the set is a study resource rather than a three-hour sitting.
