The deposition of alkali salts on the inside walls of the pipe is called incrustation. It reduces the effective diameter of the well pipe and hence reduces the discharge of the tubewell. It cannot be completely eliminated.

Incrustation of the tubewell pipes may lead to ______a)reduced dischar...
Incrustation of the tubewell pipes refers to the deposition of mineral scales, sediments, or other deposits on the inner surface of the pipes. This process can occur over time due to the presence of dissolved minerals, such as calcium carbonate or iron, in the water being pumped from the tubewell. Incrustation can have various impacts on the tubewell operation, and in this case, it may lead to reduced discharge from the tubewell.

Reduced discharge from the tubewell:
- When the pipes become encrusted, the inner diameter of the pipe decreases due to the deposition of scales and sediments. This reduction in the pipe's diameter creates frictional resistance to the flow of water, resulting in decreased discharge from the tubewell.
- The incrustation acts as a barrier that restricts the flow area, causing a decrease in the velocity of water passing through the tubewell. This decrease in velocity further reduces the discharge.

Excessive discharge of sand with water:
- In some cases, incrustation may also lead to excessive discharge of sand along with water. As the tubewell pipes become encrusted, the flow of water through the pipes becomes uneven, leading to the erosion of sand particles in the aquifer. These eroded sand particles can then be carried along with the water and discharged through the tubewell.

Discharge of highly alkaline water:
- Although not mentioned in the options, it is worth noting that incrustation can also result in the discharge of highly alkaline water from the tubewell. The deposition of minerals on the pipe's surface can change the water's chemical composition, leading to an increase in alkalinity. This can have adverse effects on the quality of water being pumped from the tubewell.

Increased pumping rate:
- Contrary to the given options, incrustation of tubewell pipes does not lead to an increased pumping rate. On the contrary, it reduces the discharge. As the pipes become encrusted, the pump has to work harder to overcome the increased frictional resistance and maintain the desired flow rate. This increased workload on the pump can lead to increased energy consumption and reduced overall efficiency of the pumping system.

In conclusion, incrustation of tubewell pipes can result in reduced discharge from the tubewell due to the decrease in pipe diameter and increased frictional resistance. It can also lead to excessive discharge of sand and possibly result in the discharge of highly alkaline water.
