## NOZZLE AND DIFFUSER CLASS NOTES FOR MECHANICAL ENGINEERING

NOZZLE AND DIFFUSER CLASS NOTES FOR MECHANICAL ENGINEERING  It is a passage of variable cross section (area decreases from entrance onward). Velocity increases and pressure decreases. This is true as long as velocity at the inlet of the nozzle is sub-sonic.  Velocity is less the velocity of sound or Mach number <1.  Diffuser is a…

## LAWS OF THERMODYNAMICS CLASS NOTES FOR MECHANICAL ENGINEERING

LAWS OF THERMODYNAMICS CLASS NOTES FOR MECHANICAL ENGINEERING Laws of thermodynamics deals with thermal equilibrium. First law deals with heat conversion into work. Complete conversion of heat into work is not possible. All process in nature are irreversible. Second law talks of irreversibility. Third law gives irreversibility is due to increase of entropy in…

## THERMODYNAMIC SYSTEMS, PARAMETERS & POTENTIALS CLASS NOTES

THERMODYNAMIC SYSTEMS, PARAMETERS & POTENTIALS CLASS NOTES A thermodynamic system is a 3-dimensional visible space in the universe. It has one or more thermodynamic process (or processes) of energy conversion from one form to other. It is mostly conversion of heat to work in all power producing devices. These devices are petrol, diesel, steam engines,…

## THERMODYNAMIC PROCESSES AND PROPERTIES CLASS NOTES

THERMODYNAMIC PROCESSES AND PROPERTIES CLASS NOTES   Any thermodynamic system works on a closed repeatable cycle. Each cycle consists of four processes. In these processes, there is transfer of heat and work into the system or out of the system. Normally processes have one variable as constant. Adiabatic process in which there is no heat…
