Measuring the Viscosity of Motor Oil ME331 Laboratory Assignment #1 Prepared for: Prof. Sangeorzan Submitted by: Abstract An experiment was conducted to model the effect of temperature on the viscosity of motor oil and compare the results to commercial values established by the Society of Automotive Engineers (SAE) for SAE 30‚ SAE 40 and SAE 5W30. The viscosity of the oil sample at eight temperatures between 20 °C and 55 °C was determined using a rotary Brookfield DV-II+ viscometer

the piece‚ and varying surface area could have a great effect on the rate of osmosis. This is because in an experiment where the potato chip has a large surface area‚ there is a larger area of partially permeable membrane and therefore more opportunity for water particles to pass through. I will keep the surface area the same by keeping the mass and length of the potato piece the same in each instance‚ by measuring and cutting it carefully. I am fairly sure that my results are reliable

The Effect of Osmosis on a Potato Cell October 12th 2012 Osmosis Lab Purpose: The purpose of this lab is to investigate the effects of osmosis on a potato cell as it is immersed for a period of time in solutions of different water concentrations. Hypothesis: If the potato is immersed into the distilled water‚ then it will be the heaviest out of the three. This is because water is at the lower is moving toward the area of higher concentration‚ which in this case is the potato. This

BACKGROUND Egg is considered as one of the most typical food stuff in the country due to its affordability and high nutritive value. Egg’s size is a very important quality parameter for the consumers’ evaluation preferences. Consumers would want eggs with accurate designated size as much as possible. Correct size classification is also useful for the people in a poultry business in terms of sorting‚ packaging planning and in imposing the price for a certain size. The size of the egg is mostly

3/1/2013 5) In response to the movie "Citizen Kane" one of the reason this film is considered one of the greatest produced is because of the many events in American History it alludes to‚ such as Yellow Journalism. Yellow Journalism was predomintaley seen throughout the 1880’s to the 1900s ‚ it was employed as a business‚ which caused editors to invent many stories that weren’t true. During this time period many newspapers were very intrested in catching the public’s attention rather than promoting

1. The five-force analysis suggests that KFC faces a very active and rigorous competition. There is extreme rivalry in the fast food industry. There are more then a hundred other fast food businesses that KFC competes with. Statistics show that there is always threat of new competition as there are new chains developing from time to time in the industry. The reason behind such a threat existing is due to the fact that the industry is a highly profitable market. There a various number of

Choose 6 bones that the chicken and human have in common – list them and their function in each organism. Choose 3 from each organism which the other does not have – list them and explain their functions and how it relates to each organism. The skeleton of a chicken and a human have many similarities and differences. Of course‚ the skeleton of a chicken is much less smaller than of a human’s therefore more bones are fragile to the chicken. Human’s bones and chicken’s bones are adapted to their

live embryonated broiler chicken eggs. Group A is negative control with no haemagglutination activity and group B as positive control with positive Haemagglutination activity. For each drug to be tested‚ 40 eggs were assigned to 8 groups (i.e. A‚ B‚ C1‚ C2‚ C3‚ D1‚ D2‚ D3) with 5 eggs in each group. Embryonated eggs in each of C1‚ C2 and C3 subgroups were treated only with 3 different concentrations of each compound to evaluate toxicity respectively. Whereas embryonated eggs of SUBGROUPS D1‚ D2 and
