Manufacturing processes-1-mechanical engineering
Aug 03, 2015 dear readers, welcome to manufacturing processes - 1 multiple choice questions and answers with explanation. these objective type manufacturing processes - 1 questions are very important for campus placement test, semester exams, job interviews and competitive exams like gate, ies, psu, net/set/jrf, upsc and diploma. specially developed for the mechanical engineering
buckingham π theorem (also known as pi theorem) is used to determine the number of dimensional groups required to describe a phenomena. according to this theorem “the number of dimensionless groups to define a problem equals the total number of variables, n, (like density, viscosity, etc.) minus the fundamental dimensions, p, (like length, time, etc.).”
dec 11, 2018 process manufacturing (continuous) process manufacturing (batch) 1. repetitive manufacturing. a manufacturer would use repetitive manufacturing for repeated production that commits to a production rate. repetitive processing is comprised of dedicated production lines that produce the same or a paraphernalia of items, 24/7, all year round.
nov 13, 2020 rather, it can be applied to the food and drinks industry, cement manufacturing, plastics industry co-extrusions, sludge treatment and virtually any process that deals with the transportation of
New pipelining method for heavy oil: stabilising the flow
based on the principles of lifecycle assessment, the method includes the characterisation of resources in the manufacturing environment and resource flow models. within the research network green factory bavaria, ten universities are working together with more than 100 companies in approximately 80 projects to increase energy and resource
Doing the math: analysis of forces in a truss bridge-lesson
In this lesson, students learn the basics of the analysis of forces engineers perform at the truss joints to calculate the strength of a truss bridge. this method is known as the “method of joints.” finding the tensions and compressions using this method will be necessary to solve systems of linear equations where the size depends on the number of elements and nodes in the truss. the
commercial production of polyethylene commenced in england during the early 1940s using a free radical process operating at very high pressures (30,000 to 50,000 psi). the structure proved to be far more complex than the simple textbook repeat unit, –ch 2 ch 2 –, would suggest . the backbone has short-and long-chain branches.
mar 29, 1999 • possible secondary equipment or process damage from equipment failure. • ineficient use of staff resources. note that more than 55% of maintenance resources and activities of an average facility are still reactive. advantages to reactive maintenance can be viewed as a
cement, all the employment associated with the concrete industry, as well as new construction projects, will be terminated. because of limited natural resources, concern over ghgs, or, both, cement production is being curtailed, or at least cannot be increased to keep up with the population increase, in some regions of the world.
Sustainability of concrete construction
replacing obsolete equipment to improve performance is an essential piece of reducing manufacturing downtime. outdated machines slow down the manufacturing process. installing new equipment should allow your plant floor to stay up-to-date on the latest technologies, which allows managers to suggest updates to improve productivity.
Soil compaction handbook
This is a significant part of the building process. if performed improperly, settlement of the soil could occur and result in unnecessary maintenance costs or structure failure. almost all types of building sites and construction projects utilize mechanical compaction techniques. these different types of effort are found in the two principle
not improve due to other causes. a key principle of performance management is to measure what you can manage. in order to maintain and improve manufacturing performance each function in the organization must focus on the portion of the indicators that they influence. maintenance performance contributes to manufacturing performance. the key
the widespread production is also due to the relatively low price and high density of cement, which in turn limits ground transportation because of high transport costs. in 1996, global cement trade was 106 mt of cement, 7% of global cement production. 2.2. process description. cement production is a highly energy-intensive process.
jun 01, 2020 1. introduction. digital fabrication with concrete has seen a rapid evolution, especially within the last few years [, , , , , , , , ].lagging productivity and shortages in skilled labor have been driving the construction industry towards industrialization .the digitization process, which includes new additive manufacturing (am), construction scale processes such as 3d printing, is playing a
Setting on demand for digital concrete – principles
jan 09, 2020 the major disadvantage of using ccs for cement clinker production is the increase of coal consumption, i.e., 515 mj/t cement clinker, and the major advantage of using ccs for cement clinker production is the resource benefit brought by co2 reduction (the avoided biotic resource damage in ecosystem), i.e., 1160 mj/t cement clinker.

cost benefit. case study shows that there is approximate, 30 % decrease in energy cost and 30 % in maintenance cost and 50 % decrease in manpower cost also. image courtesy: google. hence, it is very important to consider the importance of tpm; however there are so many others tools as mentioned below and most of company are using following
aug 18, 2021 field data shows that the daily productivity of oil wells using the new ppgs is at least 2–3 times that of wells in the same area using other sand control methods. under the same fluid production rate, the production pressure difference of the well with the prepacked gravel screen completion is only 20%-25% of gravel-packed completions around
