Paper format. 16-Mec-B3
Energy Conversion and Power Generation, National Examinations,
December 2018. Three hours, closed book. Two sections: Section A is
calculative (Questions 1–5) and Section B is descriptive
(Questions 6–8). Candidates answer four questions from Section A and two
from Section B; six questions of 10 marks each constitute a complete paper
(60 marks). Reference data for individual questions are bound in as
attachments on pages 10–12, reference formulae and constants on
pages 13–16, and Granet & Bluestein steam tables are supplied.
All eight questions are solved below, because the set is a
study resource rather than a timed attempt.
