CNG – Advantages and Disadvantages The advantages of CNG are that it is environment friendly, cheap, and easily available. However, the disadvantages are that there is no central authority in controlling the entire market of CNG. Advantages of CNG: Environmentally friendly: CNG emits 80% less CO2 and 50% less NOx than diesel. CNG vehicles produce …
Advantages and Disadvantages of Worm Gear? A worm gear is a machine tool that is used to create gear teeth. It consists of two sprockets connected by a shaft and are driven by an external gear or spur. The most common application for the worm drive is in industrial applications, where they are used to …
Difference between Galvanizing and Electroplating Galvanizing and electroplating are both used to protect certain metals against corrosion but they do so in different ways. Galvanizing is a metal finishing process that creates a surface layer of zinc on iron or steel. Electroplating is the process of depositing metal onto a surface through electrolysis or chemical …

Friction Welding – Advantages and Disadvantages? Friction welding is a process in which two parts with rough surfaces are pressed together at an angle until they touch each other and then heat is applied to bond them together. Friction welding is a process of joining metals by heating them in the presence of high-speed rotating …
Clamp coupling Vs Muff coupling – Difference Clamp coupling is a form of mechanical seal where the parts are placed in close proximity to each other and then clamped together. This creates friction between them which is strong enough to hold them together. Clamp coupling is a method of joining two parts together by means …

Difference between Viscosity and Density? Viscosity is the measurement of how thick a liquid is. It’s usually measured in units called poise (pl) or centipoise (cps). The higher the viscosity, the thicker the liquid, The higher the viscosity, the slower it flows. Viscosity is the measure of a fluid’s resistance to flow. The higher the …
Difference between LPG and CNG? LPG is the most common form of fuel used in vehicles. It is known as liquefied petroleum gas or just LPG for short. CNG stands for Compressed Natural Gas and it is another type of fuel used in vehicles. LPG is liquefied petroleum gas. It is a mixture of propane …

Difference between Resilience and Toughness? Resilience in metals is a term used to describe the ability of a metal to return to its original shape after it has been deformed. The resilience of metals is measured by using the Vickers hardness test which is based on indentation strength and hardness. The harder and tougher the …
Difference between the rigid and flexible coupling? The rigid coupling is where the axle shafts are attached to each other and there is no flexibility in movement. and it does not allow axial or radial motion in between the driving and driven shafts. A flexible coupling is where the shafts are connected by a flexible …
