Shri Giriraj Group Interview Questions and Answers

CNG compressors typically have multiple stages to increase the pressure of the gas.

• CNG compressors usually have 2 to 4 stages depending on the desired pressure output.

• Each stage of the compressor helps to incrementally increase the pressure of the gas before it is stored or used.

• Higher pressure requirements may necessitate more stages in the compressor system.

• Examples of CNG compressor manufacturers with multi-stage systems include Ariel Corporation and Ingersoll Rand.

The process of whose pipe refers to the process of determining ownership or responsibility for a particular pipeline.

• Identifying the owner of the pipe

• Determining the party responsible for maintenance and repairs

• Establishing liability in case of accidents or damages

Marketing is the process of promoting and selling products or services.

• It involves identifying customer needs and wants

• Developing a product or service that meets those needs

• Pricing the product or service appropriately

• Promoting the product or service through advertising, sales promotion, and personal selling

• Distributing the product or service through channels such as retail stores or online platforms

Piston work refers to the movement of a piston within an engine, converting pressure into mechanical energy.

• Piston work is the process of a piston moving up and down within a cylinder in an engine.

• It involves the conversion of pressure from combustion into mechanical energy to drive the engine.

• Examples include the up and down movement of a piston in a car engine or a motorcycle engine.

To prepare a smooth HR policy, focus on clear communication, employee engagement, flexibility, and regular updates.

• Clearly define the objectives and goals of the HR policy

The question is about standards used in CNG, basics of natural gas, HCV MCV operation, and gas reconciliation procedure.

• CNG standards include ISO 15403, SAE J1616, and ANSI NGV2.

• Natural gas is composed mainly of methane and is extracted from underground reservoirs.

• HCV and MCV refer to high and medium calorific value, respectively, and are used to measure the energy content of natural gas.

• Gas reconciliation procedure involves comparing the amount of gas received with the amoun...read more

A work compressor is a mechanical device used to increase the pressure of a gas by reducing its volume.

• Work compressors are commonly used in industrial settings to power tools and machinery.

• They work by drawing in air or gas and then compressing it to a higher pressure.

• Examples include piston compressors, rotary screw compressors, and centrifugal compressors.
