Why Distilled water is not circulated in the pipelines ?

1.Why Distilled water is not circulated in the pipelines ? Ans. In Fwg distilled water is generated still it is not directly used in Boiler without chemical dosing even it is free from contaminants . The reason to the question is distilled water ready absorption carbon dioxide and tends to become slightly acidic which can cause corrosion . 2. What is the highest temperature at which a fuel of 60 deg Flash point should be heated to achieve a certain viscosity? Ans. Less than 20 deg of its Flash point i.e 40 deg . And the reason is near its flash point tempeature fuel starts to vaporise 3. What is the percentage water of get distillated from 100% of sea water? Ans. It is around  50% rest do formation of brine , scale of carbonates and bicarbonates .

How does Sea Pollution affects our Shipping ?

How does  Sea Pollution  affects our  Shipping ? ''Sea Pollution'' refers contamination of sea water by the  decomposition  of wastes in the form of Chemicals , Oil , Plastics , E - Waste , Seawage , Drainage etc. Then the questions rises who is responsible ?                        Source of picture : BluePlanet.edu Now our Question is How does it affects our Shipping ?  Coming to the answer of this question lets assume a situation , Initially major source of coolant was  Sea Water but because of Polluted sea water scale formation   and corrosion started taking place in the pipelines, filters , coolers etc, which result in clogging of filters and failure of the system onboard the ship.   To troubleshoot this problem , Central cooling system is used in which we avoid direct cooling through sea water instead fresh water is circulated throughou...
