Kinematic Link - Introduction and Types

Kinematic Link – Introduction and Types

A machine is a device that is capable of converting the available forms of energy to useful work. Each part of a machine, that undergoes relative motion with respect to some other part, is called kinematic link (or kinematic element). Kinematic links help in the transmission of motion, from one machine part to another. The [...]

Diesel Cycle - Processes with p-V and T-s Diagrams

Diesel Cycle – Processes with p-V and T-s Diagrams

Diesel cycle is a gas power cycle invented by Rudolph Diesel in the year 1897. It is widely used in diesel engines. Diesel cycle is similar to Otto cycle except in the fact that it has one constant pressure process instead of a constant volume process (in Otto cycle). Diesel cycle can be understood well [...]

Decision Making Process

Decision Making Process

Decision making is the process of selecting the required course of action, from a set of available alternative scenarios, to achieve a desired organizational goal. A good manager should be capable of performing proper decision making. Steps involved in Decision Making: Decision making involves the following steps: Identification of Problem Evaluating the Problem Searching for [...]

Reheat Rankine Cycle - Processes with h-s Diagram

Reheat Rankine Cycle – Processes with h-s Diagram

Reheat Rankine Cycle is essentially a modification of simple rankine cycle. In reheat rankine cycle, the following improvements are made to increase the efficiency of rankine cycle. Lowering the condenser pressure Increasing the temperature of steam while entering the turbine Large variation in pressure between boiler and condenser Implementation of reheat and regenerative system in the [...]

Hydrogen as fuel in automobiles

Hydrogen as fuel in automobiles

Hydrogen is a colourless, odourless and inflammable gas that produces a large amount of energy, while undergoing combustion. It is the lightest gas on Earth. The calorific value of hydrogen is 141,790 kJ/kg. It is the highest for any fuel. Hydrogen is the most abundant element in the universe. About 75% of all known matter [...]

Engineering Mechanics - Introduction and Types

Engineering Mechanics – Introduction and Types

Mechanics is the branch of science which deals with the behaviour of objects at rest or in motion, under the influence of forces. Engineering mechanics involves the application of the principles of mechanics to solve real-time engineering problems. Types of Engineering Mechanics: Engineering mechanics can be broadly classified into two types. They are: Statics and [...]
