Bharat Petroleum Interview Questions, Process, and Tips for Experienced

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.

• Ohm's law is expressed as V = I * R, where V is the voltage, I is the current, and R is the resistance.

• It helps in calculating the current, voltage, or resistance in a circuit when the other two values are known.

• For example, if a circuit has a vol...read more

An internal combustion engine (IC engine) is a type of engine that generates power by burning fuel inside the engine itself.

• IC engines are commonly used in vehicles such as cars, motorcycles, and trucks.

• They work by igniting fuel-air mixture inside a combustion chamber to create controlled explosions.

• The energy from these explosions is converted into mechanical energy to drive the vehicle.

• There are different types of I...read more

ROSOV stands for Return on Sales and Operating Value.

• ROSOV is a financial metric used to measure the profitability of a company.

• It calculates the return on sales and operating value by dividing the operating profit by the sales revenue.

• ROSOV helps in evaluating the efficiency and effectiveness of a company's operations.

• It is often used by investors and analysts to assess the financial performance of a company.

• For examp...read more

Water density decreases as temperature increases.

• Water density is the mass of water per unit volume.

• As temperature increases, water molecules gain energy and move faster.

• Faster moving molecules create more space between them, resulting in lower density.

• For example, ice has a higher density than liquid water because the molecules are more closely packed.

A gate valve is a type of valve that uses a gate or wedge-shaped disc to control the flow of fluid.

• Gate valves are commonly used in industrial applications to control the flow of liquids or gases.

• The gate or disc of a gate valve moves up and down to open or close the valve.

• Gate valves provide a tight seal when closed, preventing any leakage.

• They are typically used in applications where a full flow or no flow condition ...read more

Pump working principles involve the conversion of mechanical energy into fluid energy to transport fluids.

• Pumps use mechanical energy to create pressure and move fluids.

• They work based on the principle of fluid dynamics.

• Pumps have an inlet and an outlet where fluids enter and exit.

• The pump imparts energy to the fluid, increasing its pressure and kinetic energy.

• Different types of pumps include centrifugal pumps, recipro...read more

A valve is a device that controls the flow of fluid or gas by opening, closing, or partially obstructing various passageways.

• Valves are used in various industries such as oil and gas, water treatment, power generation, and manufacturing.

• There are different types of valves including gate valves, globe valves, ball valves, butterfly valves, and check valves.

• Gate valves are used to fully open or close the flow of fluid, w...read more

A gate valve is a type of valve that uses a gate or wedge-shaped disc to control the flow of fluid.

• Gate valves are primarily used to start or stop the flow of fluid in a pipeline.

• They have a sliding gate or disc that moves perpendicular to the flow of fluid.

• When the gate is fully lifted, the flow is unrestricted, and when it is fully closed, the flow is completely stopped.

• Gate valves are commonly used in applications w...read more

HSD density refers to the density of High-Speed Diesel fuel.

• HSD density is the measure of mass per unit volume of High-Speed Diesel fuel.

• It is typically expressed in kilograms per liter (kg/L) or grams per milliliter (g/mL).

• The density of HSD can vary depending on factors such as temperature and composition.

• Knowing the density of HSD is important for various engineering calculations and fuel efficiency analysis.

• For exa...read more

EBMS density refers to the density of the Engineered Biomaterial System used in mechanical engineering.

• EBMS density is a measure of the mass per unit volume of the Engineered Biomaterial System.

• It is an important parameter in designing and analyzing mechanical components made from EBMS.

• EBMS density can vary depending on the composition and structure of the biomaterial.

• Higher density materials are generally stronger and...read more

A nozzle is a device used to control the flow and direction of a fluid or gas.

• Nozzles are commonly used in various industries such as aerospace, automotive, and manufacturing.

• They are used to accelerate or decelerate fluid flow, create a desired spray pattern, or generate thrust.

• Examples of nozzle applications include rocket engines, fuel injectors, spray painting equipment, and fire hoses.
