Question
Download Solution PDFA canal is 80 km long and has an average surface width of 15 m. If the evaporation measured in a class A pan is 0.5 cm/day, the volume of water evaporated in a month of 30 days is (in m3)
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
The volume of water evaporated (V) = E × L × B
Where, E = Evaporation measured per day, L = Stretch of evaporation & B = Average surface width
Calculation:
Given, L = 80 km = 8 × 104 m
B = 15 m
Evaporation = 0.5 cm / day
Pan co-efficient = 0.7
Total volume of evaporation (V) = 8 × 104 × 15 × 0.5 x 10-2 × 0.7 × 30 m3
∴ V = 126000 m3Last updated on May 28, 2025
