Refrigeration systems contain several safeties to protect against equipment failure, leaks, and other potential hazards. Here are some of the key safety features typically found in refrigeration systems:  Low pressure (Lp)

Processes involved in refrigeration: There are four different process involved in the main components of a refrigeration system. Working of the refrigeration system (VCRS): The air inside the room is sucked

Liquefaction: Liquefaction is a process of converting gas to liquid. It can be done by two ways:              For example; in a home gas cylinder, the gas is stored under high

Sensible heat: Sensible heat is the amount of heat required to change the temp of a substance without changing the state. When heat is applied to an object and it causes

What is Refrigeration system? Refrigeration is the process of removing heat from a substance or space to lower its temperature. This is typically achieved through the use of a refrigerant, which

Thermodynamics has a wide range of applications in various fields, including physics, chemistry, engineering, biology, and material science. Here are some of the key applications of thermodynamics- heat engine, heat pump

The Carnot cycle is an ideal reversible closed thermodynamic cycle consisting of four processes.                     1. Isothermal expansion (1-2)                     2. Adiabatic expansion (2-3)                     3. Isothermal compression(3-4)                     4. Adiabatic

What is a thermodynamic process? A thermodynamic process refers to the transformation or change that occurs in a system’s thermodynamic variables, such as temperature, pressure, volume, or internal energy. It describes

Gear pump load characteristics with example: Gear pump is used for transferring heavy fuel oil and its motor current is directly proportional to pump discharge pressure. In a gear pump discharge

What are gas laws? Gas laws are a group of laws that govern the behaviour of gases by providing relationships with volume, pressure, temperature, and no. of molecules. Some of the

The law of thermodynamics are fundamental principles in physics that govern the behavior of energy and matter in the universe. There are four laws of thermodynamics, but the first three are

What is Thermodynamics?  Thermodynamics is a branch of physics that deals with the study of energy and its transformations, particularly in relation to heat and temperature. It is concerned with the

Priming: Priming of a centrifugal pump is defined as the operation in which the suction pipe, casing of the pump, and a portion of the delivery pipe up to the delivery

WHAT IS A POSITIVE DISPLACEMENT PUMP? A positive displacement pump moves a fluid by repeatedly enclosing a fixed volume and moving it mechanically through the system. The pumping action is cyclic

NPSH is the measure of suction pressure available at the inlet side of the pump. It says that water at the pump should not vaporize due to which the suction pressure

Theoretical and actual curve (Pressure and flow rate) In the above characteristic curve we can see that as the flow rate increases pressure will be gradually decreasing, due to many factors
