Under reamed piles are bored cast-in-situ concrete piles having at least one number of bulbs framed by extending the pile stem. These piles are most appropriate in soils where significant ground developments happen because of occasional varieties, topped off grounds, or in delicate soil layers. At the point when just a single bulb is given at the … Read more
Cavitation is a process in which a decrease of pressure to or below the liquid’s vapor pressure prompts the development of little vapor-filled cavities in the fluid. When exposed to higher pressing factors, these pits, called “air pockets” or “voids”, implode and can create shock waves that may harm the apparatus. These shock waves are … Read more
It is a special type of concrete with a high porosity utilized for concrete flatwork applications that permits water from precipitation and other sources to pass directly through, thereby decreasing the runoff from a site and allowing groundwater recharge. Pervious Concrete is also known as porous concrete, permeable concrete, no-fines concrete, and porous pavement. This type of concrete is produced using large aggregates with little to no fine aggregates. … Read more
Superalloys are high-performance heat-resistant alloys. It has the great ability to work under high temperatures. They have excellent strength, high resistivity against thermal creep, high surface stability, and resistivity against corrosion. Superalloy improvement has depended vigorously on both chemical and process innovations. Superalloys grow high-temperature strength through strong arrangement fortifying and precipitation reinforcing from optional … Read more
In this process, the material is taken out by the effects of a very high-speed stream gas abrasive mixture focused on the workpiece. The high-Velocity effect of a rough molecule causes a little fragile break on the work surface and the streaming gases divert the removed little workpiece molecule. Process of Abrasive Jet Machining (AJM) … Read more
Canal fall is a solid masonry structure that is made on the canal if the natural ground slope is steeper than the designed channel bed slope. If the difference in slope is little, a single fall can be made, but If it is higher then falls are made at regular intervals. Types of Canal Falls: … Read more
There are five types of welded joints as follows: Butt Joint Corner Joint Lap Joint Tee-Joint Edge Joint Now we will discuss these types of welded joints. 1. Butt Joint: In a Butt-welded joint, the parts lie in a similar plane and are joined at their edges. 2. Corner Joint: In the corner welded joint, … Read more
There are 5 main components of the standard ball bearing as follows: Inner Ring. Outer Ring. Balls. Cage. Lubrication I have described these 5 components in brief. 1. Inner Ring: It is the smaller of the two bearing rings. There is a groove on the external diameter to make a pathway for the balls. The external … Read more
The ratio of the effective length of a column (Le) and the least radius of gyration (r) about the axis under consideration are known as the Slenderness ratio. It is indicated by the “λ” (lambda). The slenderness ratio is called about the minor axis of cross-section and major axis of the cross-section. Effective slenderness ratio of the section … Read more
Difference between reciprocating and rotary compressors should be possible in perspectives like pressing factor proportion, dealt with volume, speed of the blower, vibrational issue, size, air supply, the virtue of packed air, pressure effectiveness, upkeep, mechanical productivity, oil, introductory expense, adaptability, and reasonableness. Reciprocating Compressors Rotary Compressors The discharge pressure of the air is high. … Read more
