The pattern is the replica of the device which is the output of the casting process. This when molded in sand forms mold. After filling the mold with the molten metal there is a formation of casting. Patterns play a very important role in casting as they decide the quality as well as perfection in […]
During the casting of metals in the foundry shop we use sand for the preparation of mould. It is the moulding sand properties which improves the quality of the casting metal. If sand of suitable property is chosen, then it greatly minimises the casting defects that may be produced during the mould preparation and casting.
What is Casting Defects? It is an unwanted irregularities that appear in the casting during metal casting process. There is various reason or sources which is responsible for the defects in the cast metal. Here in this section we will discuss all the major types of casting defects. Some of the defects produced may be

What is Boyle’s Law? This law was established by Robert Boyle in 1662. At constant temperature, the absolute pressure of a given mass of a perfect gas is inversely proportional to its volume. Have you understand something from this? If not than let’s we understand what this statement implies. It means that if we have

Brakes are very crucial for stopping a vehicle. Without brakes, it is impossible to drive a car or any vehicle. Brakes are of different types and according to the requirement, the types of brakes are chosen for the application. Here we will discuss Disc brake – its main components, working, advantages, and disadvantages with the
If someone ask you a question that can you drive your vehicle without brakes? Then what will be your answer, obviously No. Driving a vehicle without brakes is impossible. Brakes are crucial for stopping a vehicle and driving safely on the road. The use of a proper braking system enhances the handling of the vehicle
What is a Perfect Gas? A perfect gas or an ideal gas is a state of a substance, whose evaporation from the liquid state is completed and which obeys all the gas laws strictly under all conditions of pressure and temperature. In reality there is no ideal or perfect gas which obeys all the law

Adiabatic process is a process in which there is no exchange of heat takes place from the working substance to the surrounding during its expansion or compression. This is possible when the working system is made thermally insulated, that is no heat can leave or enters it during the process. So we can say that
The diesel cycle was invented by Rudolph Diesel in 1893. He put forward an idea by which we can attain higher thermal efficiency, with a high compression ratio. All diesel engine works on this cycle. Diesel is used as fuel in this cycle as it can be compressed at a higher compression ratio. It is
The Otto Cycle is the ideal thermodynamic cycle used to describe how spark ignition (SI) engines, commonly known as petrol engines, operate. It was developed by Dr. Nikolaus August Otto, whose work led to the foundation of modern gasoline engines used in motorcycles, cars, and light vehicles. In simple terms, the Otto cycle explains how fuel energy is converted into mechanical
