Refrigeration and Air Conditioning

Refrigeration means keeping the sequence constant at a lower temperature than the environment. That is, in the refrigeration process, continuous heat is absorbed from the low level and given to the high level. Crude is used in th…

Second Law of Thermodynamics in Terms of Entropy

If a body or engine is taken from one curve to another curve at approximately the same temperature in such a way that dQ of heat is exchanged. This is the second law of thermodynamics in the form of entropy. Change in entropy ds …

When all the Entropy Changes in a Process are Included

When all entropy changes occur in a process, the total entropy change of the universe is always greater than or equal to zero. This is the second law of thermodynamics. In 1850, the scientist Clasius first used the word entropy, …

What is Clausius Inequality?

This is a consequence of the second law of thermodynamics, which is true for all possible cycles, including (reversible, irreversible, heat engines, and refrigerators).  We can represent any reversible cycle by a series of Carnot…

Humidity, Relative Humidity, Specific Humidity Definition

The water vapor present in the atmosphere or the water vapor present in the gas is called humidity. There are many types of humidity such as molal humidity, relative humidity, absolute humidity, saturation humidity, specific humi…

Types of Saturation in Gas

When a gas or gaseous mixture comes in contact with a liquid, it takes up vapor from the liquid. This action continues till the vapor pressure of the gaseous mixture at the present temperature becomes equal to the vapor pressure …

What are Reactants in Chemistry

A substance that takes part in a chemical reaction and changes when mixed with another substance. This post ost the types of Reactants and Reactants definition, like Limiting reactant, Excess reactant, Percent of excess reactant…

Reciprocating Pump Working, Construction and Uses

In this article, I have been told about the uses, advantages, working, and construction of reciprocating pumps which are as follows. {tocify} $title={ Table of Contents } Construction of Reciprocating pump  The main parts of the …

What is Pump and Types?

A pump is a device used to increase a fluid's pressure energy. A liquid pump generally lifts a liquid from a lower level to a higher level. So pumps do some work on the fluid, and to do the work, energy is supplied from an ex…

Define Hydraulic Coefficient of Orifice

The importance of the Hydraulic Coefficient is the three types of coefficients in fluid mechanics used to the coefficient of Contraction, coefficient of velocity, and coefficient of discharge, the relation between Cd. Coefficient…

What is Rectangular Notch or Shesporested Weir Formula

Due to the contraction at the edge of the notch or weir, the value of actual discharge is theoretically reduced. Derivation of Notch and Weir formula by immersion of velocity. Let the discharge constant be Cd  {tocify} $title={ T…

Fluid Flow Questions and Answers

Fluid questions and answers for fluids flow uses equipment parts and terms.  What is weirs in fluid mechanics? Weirs are used for fluid flowing in an open system. There is an abstraction in we…

Pitot Tube Working Principle and Pitot Tube Derivation

The pitot tube is the simplest form of Bernoulli. It is used to measure the speed of fluid flow in an open tube. It is an L-shaped bent glass tube open at both ends. Pitot Tube Working Principle {tocify} $title={ Table of Content…
