Total quality management  Total quality management  or TQM is an integrative philosophy of managment for continuously improving the quality of products and processes.It is used around the world.TQM functions on the premise that the quality of products and processes is the responsibility of everyone who is involved with the creation or consumption of the products or services offered by an organization. What does TQM mean? Total Quality Management means that the organization's culture is defined by and supports the constant attainment of customer satisfaction through an integrated system of tools, techniques, and training. This involves the continuous improvement of organizational processes, resulting in high quality products and services. Objectives : after successfully completing this seminar, participants will be able to better; Ì Explain quality management concepts, values and strategies Explain management's roles and responsibility in leading quality management Develop a pr...

STOKES FLOW    Stokes flow  (named after  George Gabriel Stokes ), also named  creeping flow  or  creeping motion , is a type of  fluid flow  where  advective   inertial  forces are small compared with  viscous  forces. The  Reynolds number  is low, i.e.  . This is a typical situation in flows where the fluid velocities are very slow, the viscosities are very large, or the length-scales of the flow are very small. Creeping flow was first studied to understand  lubrication . In nature this type of flow occurs in the swimming of  microorganisms  and  sperm . In technology, it occurs in  paint ,  MEMS  devices, and in the flow of viscous  polymers  generally. The equations of motion for Stokes flow, called the Stokes equations, are a  linearization  of the  Navier–Stokes equations , and thus can be solved by a number of w...

ULTRASONIC WELDING  Ultrasonic welding is an industrial technique whereby high-frequency ultrasonic acoustic vibrations are locally applied to work pieces being held together under pressure to create a solid-state weld. It is commonly used for plastics, and especially for joining dissimilar materials. In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together. Ultrasonic welding of thermoplastics causes local melting of the plastic due to absorption of vibration energy. The vibrations are introduced across the joint to be welded. In metals, Ultrasonic welding occurs due to high- pressure dispersion of surface oxides and local motion of the materials. Although there is heating, it is not enough to melt the base materials. Vibrations are introduced along the joint being welded. The ultrasonic effect upon the molten metal generates a smaller grain size, giving the metal more strength. Ultrasonic welding combi...

HEAT EXCHANGER  A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at different temperatures and in thermal contact. In heat exchangers, there are usually no external heat and work interactions. Typical applications involve heating or cooling of a fluid stream of concern and evaporation or condensation of single- or multicomponent fluid streams. In other applications, the objective may be to recover or reject heat, or sterilize, pasteurize, fractionate, distill, concentrate, crystallize, or control a process fluid. In a few heat exchangers, the fluids exchanging heat are in direct contact. In most heat exchangers, heat transfer between fluids takes place through a separating wall or into and out of a wall in a transient manner. In many heat exchangers, the fluids are separated by a heat transfer surface, and ideally they do not mix or leak. Such e...

GREEN HYDROGEN         This patch of desert, more than 100 miles from the nearest town, sits next to the biggest problem that green hydrogen could help solve: vast iron ore mines that are full of machines powered by immense amounts of dirty fossil fuels. Three of the world’s four biggest ore miners operate dozens of mines here. Proponents hope green hydrogen will clean up not only mining but also other industries by replacing fossil fuel use in steelmaking, shipping, cement and elsewhere. Green hydrogen is made by using renewable electricity to split water’s molecules. (Currently, most hydrogen is made by using natural gas, a fossil fuel.) The hydrogen is then burned to power vehicles or do other work. Because burning hydrogen emits only water vapor, green hydrogen avoids carbon dioxide emissions from beginning to end. In the Pilbara region of Western Australia and in dozens of spots around the globe endowed with abundant wind and sun, investors see...

SCOPE OF PIPING ENGINEERS What is the Scope of Piping Engineers? Its Types, Roles & Responsibilities, Career & Learning Options INTRODUCTION The  oil and gas sector  is one of the important sectors in the Energy Sector, it is among the eight core industries in India. It plays a very critical role in influencing decision-making for all the other vital industries. Piping systems are critical to any process plant and processing unit. Therefore, it must be constructed with precision and care. Plant efficiency is highly dependent on the ability to move liquids through pipes to various devices that work collectively. The Piping Engineering department plays a critical role in EPC companies and is involved in the production of a lot of Deliverables & Non-deliverables. An important point to be noted here is that the process department provides basic inputs to the piping discipline to deliver the desired output. As an academic subject, Piping technology is rarely taught in c...
