We know that power plants operating on thermal energy, water kinetic energy etc have several limitations in that they are dependent on availability of natural resources such as water, coal and so forth. These resources have a limited availability and also resources like water depend on seasonal variations of climate and therefore cannot be depended upon entirely. Hence nuclear energy provides an advantage over other sources of energy in such circumstances.
Our human bodies have blood running around in arteries and veins (don’t ask me which one carries pure or impure blood), which is very important for the healthy existence of the body. Similar hydraulic equipments have hydraulic fluids in their system which is very important for them. Find out more!
A fluid is a fluid so why should the compressibility of hydraulic fluid matter? Well it does matter a lot for that would change the entire dynamics of the system, and probably make it useless for practical purposes. Here is the answer to this:
You have heard the popular saying that size does matter, but in this age of miniaturization this axiom often applies the other way round. One situation where this happens is the area of nanotechnology which seemingly is a fairly recent technology. Why did I use the word “seemingly?” Find out here.
We all used to learn and enjoy this favorite poem during our school days, but did you ever realize that the very clothes you are wearing might have something in common with this jingle? Read here to learn about the journey of wool from the skin of animals, to your skin.
Most of us usually associate the concept of manufacturing with that of engineering materials and structures associated with them, for example machines, buildings, roads and so on. But there is something else without which we cannot do without, clothes. Find out how they are manufactured below.
Petrol or gasoline is used as fuel in spark ignition (SI) engines. Gasoline is a hydrocarbon with different chemical compositions. Here are the properties that a gasoline should possess to qualify for being used as fuel in SI engines.
The fuel used in a compression ignition (CI) engine is diesel, which is a type of hydrocarbon. For hydrocarbons to qualify as a fuel for the engine, they should possess certain qualities.
In spark ignition (SI) engines, petrol or gasoline is used as fuel, while in compression ignition (CI) engines, diesel is used as fuel. Petrol engines are lightweight and achieve higher speed. Diesel engines, on the other hand, are heavy engines and achieve lesser speeds. Other differences below:
In four-stroke engines the cycle of operations is completed in four strokes of the piston inside the cylinder. In two-stroke engines the cycle of operations is completed in two-strokes of the engine. Here are more differences between four-stroke and two-stroke Internal Combustion (IC) engines.
