*Note:* kW has been consistently lowercased as is standard in British English technical texts. Imperial measurement units remain as originally stated. The term "lbs/hr" has been left as is, given it's a common engineering convention. Where necessary, spacing and format have been adjusted for clarity and UK English conventions.
