According to Pascal’s law, “pressure applied to an enclosed fluid is transmitted uniformly to every portion of the fluid and the walls of the containing vessel”. A small force (F1) is applied to the piston with a small area (A1) generating a much bigger force F2 on the larger piston (refer to above figure). A very familiar … Read more
Log Mean Temperature Difference (LMTD) is a logarithmic average of the temperature difference between the hot and cold fluid streams at each end of the heat exchanger. The bigger the value of LMTD, the higher heat is transferred. The rate of heat transfer (q) = UAΔTm In the above formula, ΔTm is the log mean temperature difference. ΔTm … 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
In statics, Lami’s theorem is a condition that relates the sizes of three coplanar, concurrent and non-collinear forces, that keeps a body in static balance. Lami’s hypothesis expresses that if three forces acting at a point are in harmony, each power is corresponding to the sine of the angle between the other two forces. Consider … 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
A lubricant is a substance introduced to decrease frictional power and heat generation between the surfaces in common contact when the surfaces move. A good quality lubricating oil generally has the following properties: Appropriate Viscosity: The viscosity of oil should not alter with rising in temperature. Oiliness: It ensures adherence to the bearings and spread … Read more
The small part of items framed during the petrol refining measure is fuel gas, propane, butane, light naphtha, substantial Naptha, lamp oil, center, distillate, light gas oil center distillate, and weighty gas oil. There device bubbling temperatures of portions are recorded beneath the table. Here is the complete list of products formed during the petroleum … Read more
Spark ignition engines and compression ignition engines are the two most popular types of engines. We can differentiate between these two based on various factors such as engine speed, cycle efficiency, fuel used, time of knocking, cycle operation, the pressure generated, and constant parameter during the cycle. Check out the below table to know the … Read more
Normally, materials are subjected to external forces when they are utilized. Mechanical Engineers figure out those powers and material researchers how materials disfigure or break as a component of power, time, temperature, and different conditions. Materials researchers find out about these mechanical properties by testing materials. A portion of the significant mechanical properties of the … Read more
