Flowserve Assistant Engineer Interview Questions and Answers

Cavitation is the formation of vapor bubbles in a liquid due to rapid changes in pressure, which can cause damage to equipment.

• Occurs when the pressure of a liquid drops below its vapor pressure, causing bubbles to form and collapse

• Can cause erosion and damage to pumps, propellers, and other equipment

• Common in high-speed fluid flow applications like pumps, turbines, and propellers

Cv is the coefficient of friction, a dimensionless value that represents the ratio of the force of friction between two bodies in contact to the force pressing them together.

• Cv is used to quantify the frictional characteristics of a material or surface.

• It is calculated by dividing the force of friction by the normal force acting between the two surfaces.

• A higher Cv value indicates a higher frictional force between the ...read more

The unit of flow rate is typically measured in volume per unit time, such as liters per minute or cubic meters per second.

• Flow rate is commonly measured in units like liters per minute (L/min), cubic meters per second (m^3/s), or gallons per hour (gph).

• It represents the amount of fluid passing through a specific point in a given time period.

• Flow rate can also be expressed in terms of mass per unit time, such as kilogra...read more
