Appoids Tech Solutions Interview Questions and Answers

There are 3 levels of schedules: Level 1, Level 2, and Level 3.

• Level 1: Master Schedule - high-level overview of the project

• Level 2: Project Schedule - detailed breakdown of the project into smaller components

• Level 3: Look-Ahead Schedule - weekly or daily schedule that focuses on specific tasks

EVM stands for Earned Value Management. It is a project management technique used to measure project performance and progress.

• EVM compares the actual work completed and the budgeted work to determine if the project is on track or not.

• It uses three key values: Planned Value (PV), Actual Cost (AC), and Earned Value (EV).

• PV is the budgeted cost of the work scheduled to be done, AC is the actual cost incurred, and EV is the budgeted cost of the work actually completed.

• EVM helps i...read more

Heat transfer and mass transfer are two different phenomena in the field of engineering.

• Heat transfer involves the movement of thermal energy from one object to another due to a temperature difference.

• Mass transfer involves the movement of mass from one location to another within a system.

• Examples of heat transfer include conduction, convection, and radiation.

• Examples of mass transfer include diffusion, osmosis, and distillation.

S Curves are graphical representations of project progress over time.

• S Curves show the planned progress, actual progress, and earned value of a project.

• They are useful for tracking project performance and identifying potential delays.

• The curve is named after its S shape, which represents the typical pattern of project progress.

• S Curves can be used for various aspects of a project, such as cost, schedule, and resource allocation.

• They are commonly used in project management sof...read more

Fluid mechanics deals with the study of fluids in motion and at rest. Pumps are devices used to move fluids from one place to another.

• Fluid mechanics involves the study of how fluids behave and interact with their surroundings.

• There are different types of flow in fluid mechanics, such as laminar flow and turbulent flow.

• Pumps are devices used to increase the pressure of a fluid in order to move it from one location to another.

• Examples of pumps include centrifugal pumps, positi...read more

Distillation columns are classified based on their internal structure and operation, such as tray columns, packed columns, and fractional distillation columns.

• Distillation columns are used to separate components in a mixture based on their boiling points.

• Tray columns have horizontal trays where vapor and liquid phases come into contact for separation.

• Packed columns contain packing material to increase surface area for better separation.

• Fractional distillation columns have mul...read more
