An earthen pithcer loses 1g of water per minute due to evaporation. If the water equivalent of the pitcher is 0.5 kg and the pitcher contains 9.5 kg of water, then calculate the time required for the water in pitcher to cool to `28^@C` from its original temperature of `30^(@)C`. Neglect the effect of radiation. Latent heat of vaporization of water in this range of temperature is 580 cal/g and specific heat of water is `1 cal//g//.^@C`.
