Q.72 Identify the INCORRECT statement about prismoidal formula used to compute earthwork.

1. It is necessary to have an odd number of cross-sections to apply prismoidal formula.

2. The ratio of volume calculated by end area formula and the prismoidal formula is called as the ‘Prismoidal correction”.

3. Prismoidal formula is also known as Simpson’s rule for volume.

If there is an even number of cross sections, the end strip must be treated separately, and volume between the remaining sections may be calculated by prismoidal formula.

Correct Option: 2

Q.73 Select the INCORRECT statement pertaining to the lining of an irrigation canal.

1. Lining helps to provide a flatter hydraulic gradient to canal, and better command area.

2. Due to lining the resistance to flow increases and the velocity of flow decreases.

3. Lining minimalizes the seepage loss in the canal, more area can be irrigated.

4. Lining increases the discharge in the canal section by increasing the velocity.

Correct Option: 2
