Thermodynamics Engineering Notes
Boilers can be classified in several ways based on their design, fuel source, and purpose. Following are some common classifications: Based on Design: a) Fire Tube Boilers: Fire Tube Boilers are a popular type of boiler that utilizes hot gases produced by combustion to heat water passing through tubes within a cylindrical shell. As 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…
Law of Conservation of Energy: The Law of Conservation of Energy states that “Energy cannot be created nor destroyed in an isolated system; it can only be transformed from one form to another or transferred between objects”. This principle is critical for understanding numerous natural phenomena, providing the foundation for various scientific theories and technological…

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…
