Awater main is to be constructed with a 12.512.5% grade in the north direction and a 2020% grade in the east direction. determine the angle thetaθ required in the water main for the turn from north to east.

The angle required in the water is 32°.

Explanation:

Given that,

Grade in the north = 12.5 %

Grade in the east = 20 %

We need to calculate the angle

We know that,

Hence, The angle required in the water is 32°.
