Question
Which meteorological parameter is directly measured by
using an open pan evaporimeter in the context of irrigation scheduling?Solution
Open pan evaporimeters (e.g., Class A pan) measure the rate of evaporation. This data helps in estimating evapotranspiration and irrigation water requirements using methods like IW/CPE ratio.
Two boats A and B start towards each other from two places, 312 km apart. Speed of the boat A and B in still water are 14 km/h and 10 km/h respectively....
