Q1. 1.Tell me about your self What Is ph . It's range
Ans. 
pH is a measure of the acidity or alkalinity of a solution. It ranges from 0 to 14.
• pH stands for 'potential of hydrogen'

• It is a logarithmic scale that measures the concentration of hydrogen ions in a solution

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline

• Examples: Lemon juice has a pH of around 2, while baking soda has a pH of around 9

Q2. What is partial pressure
Ans. 
Partial pressure is the pressure exerted by a single gas in a mixture of gases.
• Partial pressure is proportional to the mole fraction of the gas in the mixture.

• It is calculated by multiplying the total pressure of the mixture by the mole fraction of the gas.

• Each gas in a mixture contributes to the total pressure independently.

• Dalton's law of partial pressures states that the total pressure of a gas mixture is equal to t...read more

Q3. What is Ideal gas law
Ans. 
Ideal gas law is a fundamental law of physics that describes the behavior of gases under varying conditions.
• It relates the pressure, volume, temperature, and number of particles of a gas.

• The law is expressed as PV = nRT, where P is pressure, V is volume, n is the number of particles, R is the gas constant, and T is temperature.

• The law assumes that the gas particles are in constant random motion and that there are no in...read more

Q4. What do you mean by work & energy As an chemical Engineer what you will do for this organisation
Ans. 
Work and energy are fundamental concepts in physics. As a chemical engineer, I will apply these concepts to optimize processes, improve efficiency, and develop sustainable solutions.
• Work refers to the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force.

• Energy is the capacity to do work and exists in various forms such as kinetic, potential, thermal, chemical, a...read more

Q5. Flow measuring device. Unit of pressure, force,
Ans. 
The unit of pressure is Pascal (Pa) and the unit of force is Newton (N).
• Flow measuring devices include orifice plates, venturi tubes, and flow nozzles.

• Pressure is measured in units of force per unit area.

• Force is a vector quantity that can be measured using a force gauge or load cell.

• In fluid mechanics, pressure is often used to calculate flow rate.

• Examples of flow measuring devices include rotameters, magnetic flow me

Q1. What is your favorite subject ? Why heat transfer is more in forced convection than free convection? How many colour in flame and why what is Bernoulli principle ? what is fluidized bed boiler? what is flu...read more
Ans. 
Answers to various technical questions related to engineering.
• Forced convection involves external forces like pumps or fans to move the fluid, resulting in higher heat transfer compared to free convection where the fluid moves naturally due to density differences.

• The color of a flame depends on the temperature and the chemical composition of the fuel. For example, a blue flame is hotter than a yellow flame.

• Bernoulli's ...read more
