Questions
Will I learn to use steam tables?
Yes. Reading steam tables and Mollier chart for wet and superheated steam is practised with examples.
Are engine performance numericals covered?
Yes. Brake power, indicated power, efficiencies and fuel consumption are solved step by step.
Is this course based on the BTEUP syllabus?
Yes. The units follow the BTEUP (Board of Technical Education, Uttar Pradesh) diploma syllabus. If your polytechnic follows a different board or a revised scheme, the centre teaches your own syllabus.
