Introduction ( history) of solar panels: Types of Solar Panels: Alexandre Edmond Becquerel is considered to be the father of solar panels, having discovered how electricity is made from sunlight in 1839. His research created a way to build solar plants that heated water to make steam for electric machines during the Industrial Revolution Becquerel’s … Read more
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 … Read more
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 … Read more
Ultrasonic machining is a subtractive manufacturing process that removes material from the surface of a part through low-amplitude, high-frequency vibrations of a tool against the material surface in the presence of fine abrasive particles. Ultrasonic vibration machining physically operates through the mechanism of microchip or erosion on the surface of the workpiece. As the abrasive … Read more
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 … Read more
