Hemani Industries Interview Questions, Process, and Tips

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

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

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

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

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

Various types of pumps include centrifugal, positive displacement, axial flow, and jet pumps.

• Centrifugal pumps use a rotating impeller to create a flow of fluid.

• Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge port.

• Axial flow pumps move fluid parallel to the pump shaft.

• Jet pumps use a combination of pressure and suction to move fluid.

• Other types of pumps include gea

The least count of vernier caliper is the smallest measurement that can be read on the scale.

• The least count is determined by the number of divisions on the vernier scale and the main scale.

• It is usually 0.1 mm or 0.02 mm for metric vernier calipers and 0.001 inch for imperial vernier calipers.

• To determine the least count, subtract the value of one main scale division from the value of one vernier scale division.

• For ex...read more

Micrometer screw gauge is used for higher precision measurements than vernier caliper.

• Micrometer screw gauge has a higher accuracy of measurement than vernier caliper.

• Micrometer screw gauge has a smaller least count than vernier caliper.

• Micrometer screw gauge is used for measuring thickness, diameter, and depth of objects with high precision.

• Vernier caliper is used for measuring length, width, and height of objects wit

During my internship, I faced difficulties in adapting to new software tools and collaborating with team members.

• Adapting to new software tools: I had limited experience with certain software tools that were used in the internship. However, I took the initiative to learn them by attending online tutorials, seeking guidance from colleagues, and practicing on my own.

• Collaborating with team members: Initially, I found it ...read more

Blower is used to move air or gas while compressor is used to compress air or gas.

• Blower is used to create a high flow of air or gas at low pressure.

• Compressor is used to compress air or gas to a higher pressure.

• Blowers are used in HVAC systems, while compressors are used in refrigeration systems.

• Blowers are used in industrial applications to move large volumes of air or gas.

• Compressors are used in pneumatic tools like

Mechanical joints are used to connect two or more mechanical parts together. There are various types of joints and processes.

• Welding joints - fusion welding, resistance welding, friction welding

• Brazing joints - torch brazing, furnace brazing, induction brazing

• Soldering joints - soft soldering, hard soldering

• Mechanical joints - bolted joints, riveted joints, snap-fit joints

• Adhesive joints - structural adhesive, pressure...read more
