Course Outcomes:

Introduction/concepts related to measuring instruments
Explain the construction & working of mechanical process of fitting and welding operations
Observe, list and illustrate various types of friction and need for lubrication
Differentiate the working of different properties of steam and different types of boilers and to produce steam and also problems on using steam tables.
Summarise the uses of steam,by application of nozzles and turbines to generation of power.

1. Measuring Instruments

Dividers:- Sizes and uses, Combination square, Bevel protractor, Universal level protractor, Sinebar, Universal surface guage, Engineers parallels, Slip gauges, Screw pitch guage, Vernier caliper, Vernier height guage – least count of the measuring tools – comparison between measuring and checking instruments.

2. Fitting and Welding

3. Friction and Lubrication

Friction in elements of power Transmission- concept of friction – different types of frictionlubrication – concept – necessity of lubrication – classification of lubricants – properties of a good lubricant – different methods of lubrication – wick lubrication – ring lubrication – splash lubrication – forced lubrication

4. Properties of Steam & Boilers

Formation of steam under constant pressure, dryness fraction and degree of super heat, specific volume.Determination of enthalpy, Internal energy, Internal latent heat.Simple direct problems on the above using tables and charts. or rejected during the above processes.Classification of Boilers – fire tube and water tube boilers- construction and working of a simple Vertical Boiler – Lancashire Boiler – Babcock and Wilcox Boiler – Boiler mountings: water level indicator – pressure gauge – safety valve – steam stop valve – feed check valve -blow off cock – fusible plug. Boiler accessories: steam trap and separator – economizer – super heater – air pre heater – feed water pump.

5. Steam Nozzles & Steam Turbines

Steam nozzles – functions – types – convergent – divergent – convergent and divergent .Steam turbines – classification – impulse – reaction turbines – working principle with line diagram of the above two types – governing of steam turbines – throttle – by pass – nozzle control.
Steam Nozzles – function(Types-convergent, divergent and convergent and divergent) Steam turbines:a) Classification with examples:i) Impulse- Construction, working, comparison ii) Reaction-advantages – disadvantagesiii) Impulse – Reaction c) Governing of turbines:i) Throttle governing ii) Nozzle governing.
