सवाल

Are numerical problems covered?

Yes. Each unit has worked examples on velocity, belts, gears, governors and balancing at diploma level.

Are graphical methods taught?

Yes. Velocity diagrams and cam profiles are drawn step by step on drawing sheets.

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.

Are numericals included?

Yes. Bernoulli, flow measurement, pipe loss, jet force and pump power problems are solved in class.

Is the lab covered here?

The lab experiments are covered in the separate Fluid Mechanics Lab course; this course is the theory paper.

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.

Will I practise on real instruments?

Yes. Instrument reading practice with vernier, micrometer, slip gauges and sine bar is done along with the theory.
