Complete 8 pages APA formatted article: The Bernoullis Experiment. The experiment demonstrates succinctly that the venture is a means for establishing flow measurement and, from which, the discharge coefficient can be derived. From the results, it is right to say that the pressure difference increases as the level of water in the manometer tubes increases.

&nbsp.Chapter 1: Introduction

Bernoulli’s principle, named after its founder, Daniel Bernoulli, asserts that “as the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. In which case, the use of Bernoulli’s equation guides the significant concepts in the definition above. The equation makes use of the relation between pressure, velocity, and elevation (height). This is different from the continuity equation, which only applies a connection between n speed of the fluid and the cross-sectional area measured for a pipe in which the fluid moves. It is worth noting that there are certain restrictive conditions to which the principle can hold. This includes, the fluid used must be frictionless at a constant density, in which case, steady flow is a must.&nbsp.

Since frictional effects are most significant when very close to the boundary layers, the use of Bernoulli’s approximation is feasible outside the boundary layers, in which case, the flow outside is guided by the combination of two forces, pressure and gravity. The concept conveyed can be explored based on the law of conservation of energy. As a result, the fluid broader section of a pipe to a constriction triggers a more significant distance movement of the contraction’s corresponding volume, thereby increasing speed. The aspects explained therein, constituting work done in both broader and narrower sections, can be summarized into the pressure and volume product. The greater rate evident leads to the higher kinetic energy of the given volume in the thinner pipe. Going by the law of energy conservation, the observed increase of kinetic energy is thereby balanced by a decrease in the pressure-volume product, as shown in Bernoulli’s equation below (Durgaiah 2002, 50).

Kinetic energy + potential energy + flow energy = constant

Theory

The centerline, while considering the assumptions that the fluid used must be frictionless at a constant density. in which case, steady flow is a must:

From the above Bernoulli’s equation, the total head (h) is obtained from summing up the pressure head (h), velocity head (HV), and elevation head (z), respectively, as depicted on the left-hand side of the equation.&nbsp.

Hi, need to submit a 2000 words paper on the topic Media Audiences: Television, Meaning and Emotion. There are several types of media audiences ranging from sports, business, education, science, lay, expert, consumers, executive, and technical audiences among others (Gorton, 2009, pp. 27). Some media channels provide products and services that appeal to many people while others reach out to specific categories of audiences. Targeting specific classes of audiences gives a media house a unique niche or position in the market. With such a niche, the media outlet is able to study its target group and plan for ways of improving audience satisfaction thereby attracting and maintaining a bigger audience.

This essay will discuss the concept of a niche in media with a specific focus on the expert audience. The expert audience is a specific audience niche consisting of well-versed individuals who are familiar with the issues a particular media is offering. This type of audience includes educated people, technicians, scientists, and other people who are abreast with the issues being discussed in a particular media. An expert audience for a sports channel, for instance, would include players, coaches, sports scientists, trainers, and other people who understand the specific type of sports (Napoli, 2011, pp. 18). This essay will endeavor to demystify the expert audience to determine how this group of individuals engages with the media. The essay will analyze how the expert audience uses, responds, and enjoys services offered by media companies. The paper will also examine different media theories and to find out how they help to understand expert audiences. This essay will be guided by the hypothesis that expert audiences are more difficult to please because they have high expectations from the media and high-quality standards that they impose on media outlets.

The expert audience consists of individuals with a diverse background with regard to their level of education, work experience, and level of skills and expertise (Gorton, 2009, pp. 39). This group of people is usually familiar with most of the issues that media outlets discuss and in most cases, they have predetermined judgments. The media has to be very advanced in their approach to sharing information in order to appeal to an expert audience. The expert audience is different from other types of audiences such as lay audiences in many ways.
