Sterling Oil Exploration & Energy Co. Interview Questions and Answers

Transformer losses refer to the energy losses that occur during the operation of a transformer.

• Transformer losses include copper losses and iron losses.

• Copper losses occur due to the resistance of the transformer windings.

• Iron losses, also known as core losses, occur due to hysteresis and eddy currents in the transformer core.

• Copper losses can be minimized by using larger conductor sizes and reducing the resistance of ...read more

Efficiency of transformer is the ratio of output power to input power.

• Efficiency is affected by factors such as core losses, winding resistance, and load impedance.

• Efficiency can be improved by using high-quality materials, proper design, and regular maintenance.

• Efficiency is expressed as a percentage and can range from 50% to 99% depending on the transformer type and application.

Non-sparking equipment and lights are used in hazardous environments to prevent explosions.

• Non-sparking tools are made of materials that do not create sparks when struck or rubbed against each other.

• Non-sparking lights use LED technology and are enclosed in a housing that prevents sparks from escaping.

• These techniques are commonly used in industries such as oil and gas, chemical, and mining.

• Examples of non-sparking too...read more

The percentage of steel in a pile varies depending on the type and design of the pile.

• The percentage of steel in a pile can range from 0% to over 90%.

• The type of pile (e.g. steel, concrete, timber) and its design (e.g. diameter, length, wall thickness) determine the percentage of steel.

• Steel piles typically have a higher percentage of steel than other types of piles.

• The percentage of steel in a pile can also affect its

Pile built-up above cut off level as per IS code

• IS code specifies the maximum allowable pile length above cut off level

• Pile length above cut off level should not exceed 3 times the pile diameter

• Built-up pile above cut off level can cause structural instability and failure

Vertical tolerance for piles as per IS code

• As per IS 2911-1:2010, the vertical tolerance for piles is +/- 25mm

• This tolerance is applicable for both driven and cast-in-situ piles

• The tolerance is measured at the top of the pile and at intervals of 3m along the length

• If the deviation exceeds the tolerance limit, the pile may need to be rejected or remedial measures taken

Pile concrete consumption tolerance depends on various factors.

• Pile diameter and length

• Concrete mix design

• Placement method

• Quality control measures

• Environmental conditions

• Tolerance typically ranges from 5-10% of estimated consumption

• Regular monitoring and adjustment of concrete consumption is necessary

Unit weight of steel is 7850 kg/m³

• The unit weight of steel is the weight of a specific volume of steel

• It is measured in kilograms per cubic meter (kg/m³)

• The unit weight of steel is 7850 kg/m³

• This value may vary slightly depending on the composition and manufacturing process of the steel

Two stroke and four stroke engines differ in their working cycles and efficiency.

• Two stroke engines complete a power cycle in two strokes of the piston, while four stroke engines complete it in four strokes.

• Two stroke engines have a simpler design and are lighter, but are less fuel efficient and produce more emissions.

• Four stroke engines have separate intake, compression, power, and exhaust strokes, resulting in better...read more

Diesel engines and petrol engines differ in fuel type, ignition process, compression ratio, and efficiency.

• Fuel type: Diesel engines use diesel fuel, while petrol engines use gasoline.

• Ignition process: Diesel engines use compression ignition, while petrol engines use spark ignition.

• Compression ratio: Diesel engines have higher compression ratios than petrol engines.

• Efficiency: Diesel engines are generally more fuel-eff...read more

A turbocharger is a device that increases the efficiency and power output of an internal combustion engine.

• A turbocharger uses exhaust gases to drive a turbine, which in turn drives a compressor to force more air into the engine.

• By increasing the amount of air entering the engine, a turbocharger allows more fuel to be burned, resulting in increased power.

• Turbochargers are commonly used in diesel engines and high-perfor...read more

Collective bargaining is a process of negotiation between employers and employees, usually through their respective representatives, to determine the terms and conditions of employment.

• It involves a group of employees bargaining with their employer for better wages, benefits, and working conditions

• The process is usually facilitated by a union or other employee representative

• The goal is to reach a mutually beneficial ag...read more
