Fertilisers and Manure Fertilisers and manure are the substances which are added to the soil to increase its fertility and make it nutrient rich so as to assure healthy growth of plants. However, used for same goal i.e., assuring health growth of plants there are many dissimilarities between the manures and fertilisers. Why we need… Read More: Fertilisers and Manure | Advantage, Disadvantage, Application »

Alternatively, a crop is a plant or a plant that can be grown and harvested for subsistence or profit. Crops… Read More: What is a Crop and its various types ? »
What is a Boiler? A boiler is a closed vessel which is used to heat a fluid (generally water). Fluid can either be heated or boiled. Output of boiler (steam or heated water/fluid) is further be used according to the requirement (like steam based power generation, central heating, cooking etc.). Classification of Boilers A). On… Read More: Boiler | Types, Applications, Characteristics »
What is a Diesel Power Plant? Diesel Power Plant is a electricity generation unit which intakes diesel as a fuel. They are basically big internal combustion engines which work on diesel cycle. They are used where supply of coal and water is low or where power requirement is very less. Essential components of Diesel Power… Read More: Diesel Power Plant | Applications, Advantages, Disadvantages, Components »
In this article we will discuss fire tube and water tube boiler. Later in the article, we will also differentiate between them. Fire tube boiler In fire tube boilers hot gases are present in the tubes. These tubes are further surrounded by water. When heated this water converts into steam. They are considered as low-pressure… Read More: Fire Tube and Water Tube Boiler | Differences »
What are Jigs and Fixtures? Jigs and fixtures are the devices which are used to increase productivity and accuracy in machining process. In general, we use the terms ‘Jig’ and ‘Fixture’ interchangeably for each other but, in reality they are both different terms and used for different applications. Let’s discuss the device Jig and the… Read More: Jigs and Fixtures | Types, Differences, Advantages »
What is Liquid fuel? Liquid fuel is a combustible substance (in liquid form) which is used to obtain thermal energy (It is fumes of liquid fuel which are combustible). This energy can further be transformed into mechanical energy. They are easy to transport and can be handled with relative ease. Fossil fuels account for majority… Read More: Liquid Fuels | Properties, Advantages, Disadvantages, Examples »
What is Brazing? Brazing is a metal joining process in which filler metal is melted and filled into the joint. Hence, joins the joint. Brazing does not melt base metal which needs to be joined. It is performed at a temperature above 450 degrees Celsius. Use of flux in Brazing Unless brazing operations are contained… Read More: Brazing | Techniques, Applications, Advantages, Disadvantages »
In manufacturing industry there are several machining operations which are performed on metal stock but, out of all these operations 20% are hole making. Machine parts require holes for several purposes. In general, we see seven types of holes in manufacturing. Through hole Blind hole Counter bore Blind hole with flat bottom Counter sink Spot… Read More: Hole Making Operations and Types of Holes »
What is Power Transmission? For any work that has to be performed we need some power (i.e. rate of energy generation or consumption). Generally, this power is generated at one place and used at several other places. Hence, we need a mode of power transmission. Generally, we have following four modes of power transmission. Pneumatic… Read More: Mechanical Power Transmission | Methods to transfer mechanical power »
