Explanation

• Porosity: Soil porosity affects water storage and drainage.
• Fine-textured soils generally retain more water than coarse-textured soils.
• Capillary tension: It influences how strongly soil retains water against gravity after excess water has drained away.
• Field capacity (FC): It is the soil moisture content remaining after gravitational water has drained.
• It is usually about 1–3 days after thorough wetting, depending on the soil.

Explanation

Formula:

Average Rainfall = Sum (Weight x Rainfall)

Given:

W1=0.10, P1=132

W2=0.16, P2=114

W3=0.12, P3=162

W4=0.11, P4=138

W5=0.09, P5=207

Calculation:

= (0.10 x 132) + (0.16 x 114) + (0.12 x 162) + (0.11 x 138) + (0.09 x 207)

= 13.20 + 18.24 + 19.44 + 15.18 + 18.63

= 84.69 mm

Explanation

• In riveted joints, the gauge line indicates the line along which rivets are positioned.
• It helps determine the arrangement and spacing of rivets across the width of a plate.
• Gauge lines are important in designing riveted joints used in structural and mechanical applications.

Explanation

• The moisture present in soil between field capacity (FC) and permanent wilting point (PWP) is called available water.
• Because plants can generally absorb this water for growth.

Additional information:

• Field Capacity (FC): The amount of water remaining in soil after excess gravitational water has drained away.
• Permanent Wilting Point (PWP): The soil moisture level at which plants can no longer absorb enough water and remain wilted.
