Reeds Marine Engineering and Technology Volume 3: Applied Thermodynamics for Marine Engineers

Description

This book covers the principal topics in thermodynamics for officer cadets studying Merchant Navy Marine Engineering Certificates of Competency (CoC) as well as the core syllabi in thermodynamics for undergraduate students in marine engineering, naval architecture and other marine technology related programmes. This new edition will cover the laws of thermodynamics and of perfect gases, their principles and application in a marine environment. This key textbook takes into account the varying needs of marine students, recognising recent changes to the Merchant Navy syllabus and current pathways to a sea-going engineering career, including National Diplomas, Higher National Diploma and degree courses.
