TYPES OF ENGINES-SPARK AND COMPRESSION ENGINES There are many types of engines. Each is for a specific purpose. Petrol engine use a spark ignition cycle. Diesel engine use a compression ignition Cycle. Spark ignition is for light duty vehicles. Compression ignition is for heavy duty vehicles. Definition of an engine An engine is a device…
TYPES OF FLUID FLOW CLASS NOTES FOR ENGINEERS There are different types of flows for a moving fluid. The study of moving fluids is quite complex, tedious and time consuming. But the analysis can be made simple by making one or more simplifying assumptions e.g., one-dimensional flow, steady-state flow, non-viscous flow, compressible and in-compressible…
REFRIGERANTS CLASS NOTES FOR MECHANICAL ENGINEERING Refrigerant causes cooling in a refrigeration system. It flows in the refrigeration system like blood circulates in the human body. There are different refrigerants for different applications. For making their study and use simple, there is a nomenclature and numbering of refrigerants. It has to have desirable properties…
