glaciated region
A bergschrund is a crevasse that forms where moving glacier ice separates from the stagnant ice or firn above.
A crevasse at the junction of a glacier or snowfield with a steep upper slope.
A bergschrund or rimaye is a crevasse that forms where moving glacier ice separates from the stagnant ice or firn above. It is often a serious obstacle for mountaineers, who sometimes abbreviate "bergschrund".

Without the actual equilibrium moisture curve provided, it's difficult to precisely identify the regions representing free moisture and unbound moisture. However, I can explain the concepts and how they might appear on such a curve.
-
Free Moisture: Free moisture refers to moisture that exists on the surface of a substance and can be easily removed by physical means such as evaporation. On an equilibrium moisture curve, the region representing free moisture would typically be the initial portion of the curve where there is a steep increase in moisture content with increasing humidity or moisture concentration in the surrounding environment. This portion of the curve indicates the rapid adsorption of moisture on the surface of the substance.
-
Bound or Unbound Moisture: Bound moisture, also known as unbound moisture, refers to moisture that is held within the molecular structure of the substance and requires more energy to remove, such as heat during drying processes. On an equilibrium moisture curve, the region representing bound or unbound moisture would typically be the later portion of the curve where there is a gradual increase in moisture content with increasing humidity or moisture concentration. This portion of the curve indicates the saturation of the substance with moisture, where additional moisture is being absorbed into the internal structure of the substance.
In summary, the initial steep portion of the equilibrium moisture curve typically represents free moisture, while the later gradual portion represents bound or unbound moisture. However, the precise appearance of these regions on the curve would depend on the specific properties of the substance and the conditions of the equilibrium moisture experiment.

A kinetic head gets converted into static head.
C mean velocity remains constant.
D moving stream gradually reduces velocity.
ANS:A - kinetic head gets converted into static head.
The volute of a centrifugal pump should be designed in a fashion such that the kinetic energy of the fluid gets converted into pressure energy (static head).
Explanation:
-
Kinetic Head to Static Head Conversion:
- As the fluid exits the impeller of a centrifugal pump, it possesses kinetic energy due to its velocity.
- The volute casing of the pump is designed to gradually convert this kinetic energy into pressure energy (static head).
- This conversion is achieved by allowing the fluid to decelerate and expand in the volute, thereby increasing the pressure of the fluid while reducing its velocity.
-
Moving Stream Gradually Reduces Velocity:
- This statement is partially correct but does not fully describe the purpose of the volute. While the fluid does reduce velocity in the volute, the primary objective is to convert kinetic energy into pressure energy, not solely to reduce velocity.
-
Mean Velocity Remains Constant:
- This statement is incorrect. In the volute, the velocity of the fluid typically decreases as kinetic energy is converted into pressure energy. The mean velocity does not necessarily remain constant; it decreases as pressure increases.
-
None of These:
- This option would be incorrect because the purpose of the volute in a centrifugal pump is indeed to convert kinetic energy into pressure energy.
Conclusion:
The design of the volute in a centrifugal pump is crucial for efficiently converting kinetic energy (velocity) of the fluid exiting the impeller into pressure energy (static head). Therefore, the correct answer is kinetic head gets converted into static head.
