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

examples‚ assess the success of strategies adopted to resolve conflicts of interest in the management of water resources in trans-border river basins. Water conflicts often enough results from opposing interests of water users. This is especially true in trans-border river basins where the freshwater river travels across more than one country. Conflicts among water users arise as water quality or water quantity degrades and no longer meets the demands of each country. Today we will be discussing on

colloquium “Charity Water‚” by Cubby Graham. In this colloquium‚ Graham talked about 800 million people who didn’t have access to clean‚ safe drinking water. Diseases such as e. Coli‚ Salmonella typhi‚ and schistosoma were found in the water that they were drinking from. They shared the same water with the animals as well. People were also battling with leaches stuck in their throat from drinking the water. Graham talked about this one little girl from India that kept vomiting the water she was drinking

both these things water is needed so exploration of Mars by space probes has concentrated on looking for water. Humans have searched for evidence of water on Mars for many years. In 1895 American astronomer Percival Lowell thought that he had seen canals on the surface of Mars. These were disproved as tricks of the eye. Spacecraft in the 1960’s and 1970’s reported that Mars was very dry. However‚ spacecraft in the 1970’s to the 1990’s started to report evidence of water‚ either past or

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

of Alcohol vs. Caffeine on Water Flea ’s Heart Rate. Title Page Abstract For our most recent experiment we tested the effects of immersing water fleas in caffeine and alcohol to see the effects on their heart rate. Before the experiment we hypothesized that if you place the water fleas in alcohol then their heart rate will slow down‚ and if you place them in caffeine then their heart rate will raise. For this experiment we needed water fleas‚ tap water‚ two pipettes‚ a microscope
