Viscosity Lab Report Essay Example

Viscosity Lab Report Essay Example Viscosity Lab Report Paper Viscosity Lab Report Paper The distance at which the sphere was dropped from, could have affected the terminal velocity. By doing a reverse engineering calculation using the equation given in the lab sheet for Castro oil (0. 65 NSA/AMA ) , it appeared that the time needed to get this viscosity could reach to about 12 seconds. This was quite impossible in our experiment to be obtained. Accordingly, one possible justification for this problem could have been the liquid unknown type, which we assumed to be Castro. The experiment objective in principal was achieved and many new techniques were learned and developed. Finished completely. All the record result were fine but with some error percentage suitable to some different factors, one way is to rope the spheres just above the surface to reduce the increase in velocity, also the errors can be minimized by recording the timings precisely and increasing the number of repetition of the time recording to get an accurate average. Even though doing these methods to reduce the error percentage there will still be some minor errors. This experiment developed our way of thinking and knowledge, where this experiment is a minimized example for the velocity of different types of fluids in pipes due to its viscosity and the floating of liquids above water or under water due to its density.

A Brief Biography of Princess Diana

A Brief Biography of Princess Diana Who Was Princess Diana? Princess Diana, the wife of British Prince Charles, endeared herself to the public through her warmth and caring. From her picture-perfect wedding to her untimely death in a car accident, Princess Diana was in the spotlight nearly at all times. Despite problems with so much attention, Princess Diana tried to use this publicity to bring attention to worthy causes such as the elimination of AIDS and landmines. She also became truly a princess of the people when she publicly shared her struggles with depression and bulimia, becoming a role model for those who suffer from those ailments. Dates July 1, 1961 - August 31, 1997 Also Known As Diana Frances Spencer; Lady Diana Spencer; Her Royal Highness, the Princess of Wales; Princess Di; Diana, Princess of Wales Childhood Diana was born in 1961 as the third daughter of Edward John Spencer and his wife Frances Ruth Burke Roche. Diana grew up in a very privileged family that had a long history of close ties with the royal family. When Dianas paternal grandfather passed away in 1975, Dianas father became the 8th Earl of Spencer and Diana gained the title of Lady. In 1969, Dianas parents divorced. Her mothers affair helped the court decide to give custody of the couples four children to Dianas father. Both of her parents eventually remarried, but the divorce left an emotional scar on Diana. Diana attended school at West Heath in Kent and then spent a short time at a finishing school in Switzerland. Although she was not an excellent student academically, her determined personality, caring nature, and cheerful outlook helped her through it. After returning from Switzerland, Diana rented an apartment with two friends, worked with children at the Young England Kindergarten, and watched movies and visited restaurants in her free time. Falling in Love With Prince Charles It was about this time that Prince Charles, in his early 30s, was under increasing pressure to choose a wife. Dianas vibrancy, cheerfulness, and good family background caught the attention of Prince Charles and the two began dating in mid-1980. It was a whirlwind romance for on February 24, 1981, Buckingham Palace officially announced the couples engagement. At the time, Lady Diana and Prince Charles seemed truly in love and the whole world was awed by what seemed like a fairytale romance. It was the wedding of the decade; nearly 3,500 people attended and approximately 750 million people from around the world watched it on television. To the envy of young women everywhere, Lady Diana married Prince Charles on July 29, 1981, at St. Pauls Cathedral. Less than a year after the wedding, Diana gave birth to William Arthur Philip Louis on June 21, 1982. Two years after William was born, Diana gave birth to Henry (Harry) Charles Albert David on September 15, 1984. Marriage Problems While Diana, now known as Princess Di, quickly gained the love and appreciation of the public, there were definitely problems in her marriage by the time Prince Harry was born. The stresses of Dianas numerous new roles (including wife, mother, and princess) were overwhelming. These pressures plus the extreme media coverage and post-natal depression left Diana lonely and depressed. Although she tried to maintain a positive public persona, at home she was crying out for help. Diana suffered from bulimia, cut herself on her arms and legs, and made several suicide attempts. Prince Charles, who was jealous of Dianas extra media attention and unprepared to handle her depression and self-destructive behavior, quickly started to drift away from her. This led Diana to spend the mid- to late-1980s, unhappy, lonely, and depressed. Dianas Support of Many Worthy Causes During these lonely years, Diana tried to find a place for herself. She had become what many describe as the most photographed woman in the world. The public loved her, which meant that the media followed her everywhere she went and commented on everything she wore, said, or did. Diana found that her presence comforted many who were sick or dying. She dedicated herself to a number of causes, most especially to the elimination of AIDS and landmines. In 1987, when Diana became the first famous person to be photographed touching someone with AIDS, she made a huge impact in dissolving the myth that AIDS could be contracted merely by touch. Divorce and Death In December 1992, a formal separation was announced between Diana and Charles and in 1996, a divorce was agreed to which was finalized on August 28. In the settlement, Diana was given $28 million, plus $600,000 per year but she was to give up the title, Her Royal Highness. Dianas hard-won freedom did not last long. On August 31, 1997, Diana was riding in a Mercedes with her boyfriend (Dodi Al Fayed), bodyguard, and chauffeur when the car crashed into a pillar of the tunnel under the Pont de lAlma bridge in Paris while fleeing from paparazzi. Diana, age 36, died on the operating table at the hospital. Her tragic death shocked the world. Initially, the public blamed the paparazzi for the accident. However, further investigation proved that the primary cause of the accident was that the chauffeur had been driving under the influence of both drugs and alcohol.
