Abstract
Trains are equipped with water lines in all compartments, but not drinkable. This new approach helps the water drinkable by purification of the water from the lines with a separate provision to purify it, the new system obtains the purified water and stores in an overhead tank. The consumer has the choice of choosing the quantity&temperature of water. Choosing the inputs by the consumer, the quantity&nature of water is decided and sent to the microcontroller. Then with multiples of Rs.5 as activation key for the process to start, the choice of temperature is chosen as warm or cold or plain&the respective tanks are opened and closed to obtain the preferred water temperature and quantity. The whole system of temperature preference is with the mixing of water at various temperatures. The heating&cooling process of the water is the same traditional methods but the attainment of specific temperature is by the heat&mass transfer principles of water. This system is motived to be implemented on railways because of surplus water availability, a good source of income to the government and to avoid the usage of plastics in any form to store water.
Highlights
Water provision is made available by the Indian government
The climatic conditions in train journey changes with location even at constant time periods of a year. 90% of diseases are waterborne in India, to avoid disease and to give a preference of warm and cold water in drinkable state in railways is highly recommended and a source of income for government if offered at affordable rates
To obtain the desired degree of hotness or coldness, Plain water is mixed with the exact amount of hot or cold water at calculated timing with actuated valves of the storage tanks
Summary
Water provision is made available by the Indian government. The climatic conditions in train journey changes with location even at constant time periods of a year. 90% of diseases are waterborne in India, to avoid disease and to give a preference of warm and cold water in drinkable state in railways is highly recommended and a source of income for government if offered at affordable rates. To make use of the water available, a water purifier fit with the designed water dispenser[1] which offers warm and cold water. With the mere control of levers connected in with the stepper motors, the water is mixed in an appropriate quantity for the desired output. The temperature is checked for the right desired temperature fixed for warmness and the coldness[1]
