  4. Guidelines & Rules for open ended conference Write one statement or few lines related to (any) Chemical Engineering process or processing unit which may include process introduction application Cost benefit analysis pros and cons Diagrammatic representation latest trends And.....no limits Collective (joint) effort from all participants should be such that, none of the topic remain untouched. Your creative and innovative approach will lead to an interesting presentation in just few sentences. Do not repeat which has been already posted before your post Preference to English language only Do not post twice... If needed edit your already written post. 3 Participants each from Lucky draws will be chosen and awarded Amazon gift card $5 (375 INR), but they must have 5 likes to their posts Look forward for your active participation... and please do encourage all your mechanical engineer friends to participate Please appreciate the post of other members by liking the same. I am writing the first statement to give it a start Visbreaker A visbreaker is a processing unit in an oil refinery whose purpose is to reduce the quantity of residual oil produced in the distillation of crude oil and to increase the yield of more valuable middle distillates by the refinery
  5. What is a muff coupling ? A muff coupling / Sleeve Coupling is the simplest type of rigid coupling, consisting of a hollow cylinder with the same inner diameter as the shaft.It is fitted over the ends of the two shafts by the means of a gib head key. Power is transmitted from one shaft to the other shaft by means of a key and a sleeve or muff. A muff coupling is also known as a sleeve or box coupling. It is a type of rigid coupling which consists of a sleeve and a key used to connect the input and output shafts. The sleeve or muff coupling is designed as a.... Mcqs questions come in the exam with options A.thick cylinder B.dun cylinder C.Hollow shaft D.Solid shaft Answer wil be hollow shaft . The sleeve or muff coupling is designed as a hollow shaft. Function of muff coupling It is used to connect two shafts which are perfectly in axial alignment for transmitting power. Parts 1.Key 2.Shaft 3.Muff

  7. Find solutions to curb South Africa's water crisis. Develop cost effective and economic measures of seawater desalination by reverse osmosis.
  8. I would like to build a sensor machine that enables people who don't see to navigate their way around obstacles, by replicating the navigation system as used by bats
  9. I have interest in energy and CO² optimisation on outdoor pollution control systems in the cement manufacturing sector. Currently, I'm working on the design and development of a mechanical system with zero electrical energy to perform same role as the electrically powered rotary airlock. This will help in reducing the frequent production downtime, electrical energy, and dust emission to the atmosphere.
  10. I'd like to work to develop a solution for water stress in north African region with the biggest desert in the world, less agriculture areas, less clouds, less rain and snow during less than 3 months per year.
  11. I want to solve the problem of people not able to go to barber for a haircut when they already have a trimmer at their place. what we can do is create a software for trimmer to to cut hair according to the particular style you want.
  12. Looking for A new jop in civil Engineering 

  13. It is the amount of deviation from the ideal gas equation of state, PV=nRT. Adding the compressibility factor, Z, yields PV = Z nRT If the compressibility of some quantity of air n=1, at 30 Bara is 0.82 and 273 °K, then its volume will be V = 0.82 x n x R x 273 / 30, or 82% of the volume of an ideal gas. Where R is the universal gas constant. https://en.m.wikipedia.org/wiki/Compressibility_factor
  14. Gasoline, or petrol, ignites too soon (predetonation) in a diesel engine due to diesel engines high compression ratios. That causes some reverse loading, very high stresses, mostly on the cylinder rods which may eventually fail in high compression load and bearing wear. Multifuel engines must be designed for extra high rod loads.
  15. The first part of the question is comparing two completely different pipe lines of different diameter. The small pipe diameter needs more pressure to move the same flow rate. Bernoulli principle applies to points within the same pipe line. When both pipes are within the same pipeline pressure is lower in the small diameter pipe, but compared to what? Compared to the larger pipe upstream, the pressure will be lower. Why? Because energy (in this case pressure, or potential energy, from an upstream point must be used to accelerate the fluid as it moves into the smaller area of a smaller diameter pipe. So the pressure there in the smaller diameter pipe will be lower than the upstream point, but velocity will also be higher. Potential energy was converted to kinetic energy, which has increased just as much as its potential energy (pressure) has decreased. Should the next part of the pipeline get large again, then the small pipe's kinetic energy from its high velocity will be converted to higher pressure as the velocity slows down and enters the large diameter. To make this all right and proper, you must think in terms of total energy, which is always the same in pipes of both large and small diameters, as long as they carry the same flow rate and that there will be variations of how much of that energy is kinetic and how much will be potential energy when you have changes of diameters in the same pipeline.
  16. chemical engineering RX Marine was established in 1996 in Mumbai, India; as chemical manufacturing company catering exclusively to the needs of the marine industry. In a short span of 12 years the company has established itself as one of the leading wholesale suppliers of a wide range of chemicals for - Marine industry internationally - and other local industires and plants.

  19. At this particular moment I only wish to make An economical portable oxygen concentrator. A machine to detect COVID-19 symptoms analyzing in One to Two hour maximum an electrical reactor to break COVID-19 DNA
  20. Hello every one As a passionate engineer, which problem (of the world) you want to solve... Do write and explain in the most innovative way.... you can also mention the hurdle you facing or the milestone you have already achieved in solving the problem....
  21. How reliable is the center of gravity calculation in Autocad for a solid 3d model with command MASSPROP
  22. You’re all right, but there are multi fuel outboard engines (based on petrol engine design) used in defence running on various fuels, kerosene, jet fuel or diesel (low compression ratio with spark plug support). Downside is that the engines are not compliant to enviro regulations, due to incomplete combustion (engines are “Smokey”). See Mercury Racing Optimax JP and Evinrude E-TEC.
