Title Impact of water jet Objective The purpose of this experiment is to demonstrate the application of the momentum equation. The force generated by a jet of water deflected by an impact surface is measured and compared to the momentum change of the jet. To relate: • Direct measurement of impact forces • Effect of flow rate and velocity • Effect of various deflection angles Introduction / Theory Newton’s Second law states that The applied forces is equal

11.1 Washing with cold distilled water Washing process is not only remove soluble protein‚ fat‚ and pro-oxidant‚ but may also remove antioxidant. Therefore the oxidative stability of muscle ultimately depends upon the antioxidant/prooxidant balance that remains after the muscle is washed. It suggests that washing may promote oxidation in mince since it effectively removes antioxidants from the fish. In addition‚ the neutral lipids are more easily removed than polar lipids‚ phospholipids and free

diminishing rapidly. Water is one element which‚ is declining in the face of human onslaught. India’s historic billionth baby has not led the government to take concrete measures to control this rapid population growth. Jabalpur is located in the heart of Madhya Pradesh and lies 15 kilometres from river Narmada. Its present population is 2 million. Two decades back it was 700‚000. Increasing population is making summers seem like a nightmare. Though‚ in some areas of the city water supply is irregular

Fluoride In Water What? Fluoride in water! I though fluoride is where you put in toothpaste to brighten your teeth. That’s what I used to think. After reading and researching of water fluoridation‚ is a shocker. Water fluoridation is the process of putting appropriate amount of fluoride in water to control tooth decay. Since the 40’s‚ researcher have claimed that by adding moderate amount of fluoride to the water supply can help toughen the enamel of teeth and preventing tooth decay. By drinking

The privatization of fresh water creates a global system of ‘have and have not’s Water privatization creates a world where people ‘have’ access to water and those whom ‘do not have’ access to fresh water. Water privatization schemes throughout the world have a track record of exceedingly high prices‚ creation of water monopolies‚ and deteriorating quality and service and this does support the global system that water privatization creates of have and have not’s. Water privatization can negatively

“By 2015 half of the world will be short of water” Mohammed Allaf As the population of the world grows and grows and has reached the 7 billion mark‚ more and more fresh water is needed for the population to be used for drinking‚ cooking‚ washing and all the day to day uses of water. Thus trying to find fresh water has become a major threat because of the heavy consumption and need. And as this happens the poorer countries would be affected the most because of their inability to fund to
