    I'v had a discussion with a friend about how much water will evaporate from a 4m x 10m long plate, that is sprinklet with water.
    He claims only 200l/10h with 40celcius, where I claim there's least 1m3 under same conditions.

    Am I wrong or right?

    From the information given you could both be wrong or right.

    What is the relative humidity?
    At what rate is water sprinkled?
    What is the wind speed?
    What is the plate made of - does the sprinkled water form a film?
    How big are the droplets?
    Is the plate maintained at 40C or the air or the sprinkled water, all of the above?
    What additional information did your teacher give you?

    What is the relative humidity?
    It would range from bone dry conditions, to coastal areas.

    At what rate is water sprinkled?
    It's a theoretical project, there are no data, only theory, sorry.

    What is the wind speed?
    Only what a wind fan can provide of sucktion.

    What is the plate made of - does the sprinkled water form a film?
    Undecided material, but the water should make a covery film all over the plate.

    How big are the droplets?
    There are no droplets as there should in theory be a continiously water beam showering the plate.

    Is the plate maintained at 40C or the air or the sprinkled water, all of the above?The temperature in the shade should be least 40c, the plates should in theory be cooled by the continious showering of water and evaporation.

    What additional information did your teacher give you?
    There are no teacher, only my weird thoughts.

    Yeah, a lot more data will be required to calculate the evaporation rate...

    Hmmm!

    Never thought it would be that complex to calculate.

    yeah it is difficult to calculate.
