Introduction: Movement is defined as a change in position over some period of time. In terms of physics and mechanics, this is called velocity. It is defined as a change in location over some time. Rotational motion is concerned with bodies moving around a fixed axis. These bodies in the rotation session often give the…

Boiler classification Definition and introduction of boiler: Electric and steam boilers, such as those of ancient trains and ships, were used to power transportation.The first models were called “Scotch Marine,” and some of the first fire tube boilers were made of stainless steel tubes that were welded together.The same boiler is closed from which the…
An overview: The refrigeration cycle is a simple yet incredibly smart and useful process. In its simplest form, the refrigeration cycle consists of just 4 introductory factors to complete the circuit A compressor. A condenser. An expansion device. An evaporator. That is it. Well, that is it, we also need a coolant to circulate…

Introduction to vapor compression refrigeration: The compression refrigeration cycle consists of circulating a liquid refrigerant through four stages of an unrestricted system. As the refrigerant circulates through the system, it alternatively compresses and expands, changing its state from liquid to vapor. As the refrigerant changes state, the system absorbs and expels heat, reducing the temperature…
The Law of Conservation of Energy: Everything You Need to Know About the First Law of Thermodynamics The law of conservation of energy states that energy can neither be created nor destroyed. Rather, it can only change forms or be transferred from one object to another. It is also known as the first law of…

LIMITATIONS OF THE FIRST LAW OF THERMODYNAMICS The first law of thermodynamics based on the law of conservation of energy has proven to be a powerful tool for thermodynamic analysis. But over the time that it has been applied to some real systems, it has been observed that, theoretically, the first law holds for processes…
