less than that in India

That is a totally impossible question to answer as it is dependent on so many different factors!!
Heat - the warmer it is, the faster evaporation will occur. The hotter it is, the more water the air can hold.
Humidity - the more humid it is, the slower evaporation will occur. The air can only hold so much water, so if the air is already fairly full of water, not so much will be able to evaporate.
Wind speed - the windier it is the faster evaporation occurs. This is because the wind moves already evaporated water away from the site allowing more to evaporate as it reduces the humidity locally.
There are a few other factors, but those three are the main ones that will determine the rate.

It depends on so many things (like how sunny it is, how windy it is, how humid it is, does the field have long grass that may shade the surface of the water?) surely there isn't just the one rate.
Besides, how long water stays on the ground depends more than just the rate of evaporation. The type of soil determines water absorbtion, and also gradient of the ground determines water run-off.

the speed of evaporation is dependant on a number of aspects: (a million) Temperature of the water. the hotter it truly is, the swifter that is going to evaporate. At boiling aspect (one hundred levels celsius at sea aspect) it jumps to an exceedingly extreme fee of vaporization. Even frozen water will convert to a gas at a low fee in a procedure called sublimation. (2) Air rigidity. As air rigidity decreases, water will evaporate better rapidly. that's the reason many nutrition programs have guidelines for education at sea aspect besides as larger elevations (e.g. Denver it truly is a million mile in elevation). in case you've been camped on Mt. Everest, it may take you an exceedingly couple of minutes to boil a pot of water. contained in the vacuum of area, water vaporizes very rapidly. in case you've been floating up there without safe practices, your blood may boil. Wind may actually help to enhance the speed of evaporation because it has a tendency to diminish air rigidity contained in the vincinity of the position the position it truly is blowing, and that is going to also push away the air that has already soaked up water vapor on the water floor. (3) Humidity. On a damp, sticky day, water evaporates significantly better slowly than even as it truly is dry. (4) Water purity. some supplies even as further to water will replace its boiling aspect and also the speed at which it evaporates. So i'd imagine your astounding thanks to restriction evaporation is to save the temperature low (using shade, and making the water aspect deep), and to objective to protect it from wind. putting it close to to a construction or fence may help save the wind away. one project you could attempt is to operate something to the pond like lily pads (genuine or man made). The third link below includes information about a product called the pretend Lily Pad gentle that floats on water. See very last link for an area that sells residing lily pads.

I doubt if you'll get any sensible answers here Mike.
However, can't knock you for having faith in people !
Try the Environment Agency, they have all sorts of facts like this. They helped us when we were working out how much we'd loose from our field ponds during the summer, so we knew where to put the shelves. They were very helpful - I'd say contact you local office rather than a central admin office.

Can't answer that as it depends, if on nothing else, on the level of humidity and the air temperature.

Depends if it is raining or not, because if its raining who cares? It wouldn't be fast enough to stop you getting wet
