(2 Questions)

  • Q1. How pumps work?
  • Ans. 

    Pumps are devices that use mechanical action to move fluids from one place to another.

    • Pumps work by creating a pressure difference to push fluids through a system.

    • They typically consist of an inlet, an outlet, and an impeller or rotor.

    • The impeller rotates, creating centrifugal force that pushes the fluid outwards.

    • Positive displacement pumps use reciprocating or rotary motion to move fluid in discrete volumes.

    • Examples o...

  • Q2. Draw Stress Strain graph
  • Ans. 

    A stress-strain graph shows the relationship between stress and strain in a material.

    • The graph typically has stress on the y-axis and strain on the x-axis.

    • It starts with a linear elastic region where stress is directly proportional to strain.

    • Beyond the elastic limit, the material enters the plastic region where permanent deformation occurs.

    • The graph may show a yield point, ultimate tensile strength, and fracture point.
