Glycol Chillers Working Principle
Glycol Chillers Glycol chillers are one of the many refrigeration systems we can currently find in the market. As the name suggests, this type of chillers base their operation in the use of glycol. But before we learn how they work, let’s understand why glycol. What is glycol? Glycol is a translucid and slightly thick chemical compound [...]
Constant Force Springs Design and Applications
Constant force spring, as the name implies, is used to refer a spring that experience and exhibits near-constant force over its range of motion. The concept behind constant force springs stems from metal strips that have undergone a series of changes. Which in return create tension in the metal strips, enabling them to execute that [...]
Working Principles of Vapour Absorption Refrigerant System
Vapor absorption refrigeration is suitable where an inexpensive source of heat energy is easily available. In these cases using the heat directly as the operating energy is the common practice. The powerplants where heat from the co-generation process is available can use VARS. Steam turbine power plants can use the waste heat to run the [...]

301 Full Hard Stainless Steel Properties
SS 301 is a austenitic chromium-nickel steel. 301 Stainless steel is cold rolled and found in different grades – 1/2 hard , 1/4 hard , 3/4 hard and full hard. In this article I am very much keen to discuss about the SS 301 full hard. SS 301 is not magnetic when annealed but it becomes magnetic after cold working. It is available in [...]
What’s the difference between the brake and the clutch?
Brake and clutch are the two different components used in automotive . These two elements serve two different purposes. Though their functions are entirely different, both are needed for the smooth running of a automotive vehicle . What is Brake ? Simple Principle of Braking System Brakes are generally used to halt the rotating wheels [...]
What is The Physical Significance of Grashof Number ?
Grashof Number is a non-dimensional number used both in fluid mechanics and heat transfer. This number is frequently used in cases where natural convection is involved. It is named after a German engineer Franz Grashof. There are many dimensionless groups or numbers available which come into play according to the respective dominant [...]
