How to estimate the concentration of a in the reservoir

 

Civil Engineering

Wastewater of a town is directly discharged into a reservoir, which has a volume of
50*106 m3. The retention time of the reservoir water is 2 years. The 350 residents
of the city, each generate an average of 70 kg/year of contaminant A, all of which
is discharged into the reservoir with the town’s wastewater. The rate constant for
decay of contaminant A in the reservoir is k=1.5 (1/year). Assuming the population,
discharge rate, and reservoir conditions have been stable for a long time, estimate
the concentration of A in the reservoir.

Civil Engineering

You are the Chief Civil Engineer for the Enhanced Protein Production Plant on the
planet Zog where the gravitational constant is 15 ft/s2. A protein storage tank has
developed a structural problem and must be drained. There is a 6 inch diameter
orifice near the bottom of the tank that can be opened, which will allow a free
discharge (Torocelli experiment) of the liquid protein from the tank. You estimate
that the coefficient of discharge (CD) for this orifice is 0.5. The tank is a
truncated cone whose diameter is 15 ft at the centerline of the orifice and 5 ft at
the top of the tank which is 10ft above the orifice and the tank is completely full
. Estimate the time, in minutes, required to drain the tank to the level of the
orifice.

Evaluate concepts of the melting pot and the american mosaic

Evaluate concepts of the melting pot and the american mosaic

Discussion Board Assignment

In 1908, playwright Israel Zangwill referred to America as a melting pot. Zangwill’s concept of the United States as a country where people of all cultures and nations are free to come and contribute to a common American culture remains a popular concept-even more than a century after its introduction.

More recently, the concept of the American mosaic asserts that American society consist not of melting pot in which people and cultures mix together to form a larger American culture, but as a mosaic in which ethnic groups come to the United States and coexist with other groups but maintain significant cultural and social distinctions among themselves. Post a discussion that explores these themes by demonstrating how various cultures and ethnicities have contributed to modern American history and culture.

Use the following outline to format your response:

Paragraph 1

Select 1 ethnic group.

Explain a specific contribution that this group made to American society or culture.

Paragraph 2

Evaluate the concepts of the melting pot and the American mosaic.

Which concept more accurately reflects the experiences of the ethnic group you chose? Support your assertion.

Respond to at least 2 or more of your classmates’ Discussion Board postings. Be sure to respond to your classmates’ postings with substantive and respectful responses.

Explaining the reconstruction era

Explaining the reconstruction era

In the immediate years following Reconstruction, most people viewed it as a failure. In recent decades, many historians have begun to reconsider this statement. Examine the social and political events that occurred during this time period. Then, identify and discuss an event that occurred during this time period and its immediate impact on Americans during that time.

Why was u.s. so much slower than europe to create a massive

Why was u.s. so much slower than europe to create a massive

respond to ONE of the following questions in a post of no fewer than 150 words and a second substantive (150+ words) post to another student.

The United States prides itself on support of democracy and the protection of human rights. How did the United States reconcile this view with the annexation of foreign territories during the late nineteenth and early twentieth centuries? Support your response with at least two examples. Part B: Think about American foreign policy today. Compare it to the examples you used in Part A. How has foreign policy changed? Support your response with one current foreign policy issue or action.

Women have had the right to vote in the United States for not quite 100 years – since 1920. It took suffragists many years to finally achieve a constitutional amendment giving women this right. Why did men resist the idea of women voting for so long? What issues finally helped the movement gain momentum and succeed? Part B: How did giving women the right to vote influence civil rights and politics in the United States? How might politics today be different if women were not involved?

Everything discussed in this week can be connected in some way to current events and issues. Think about your life – potential or current career field, daily activities and interests, freedoms and rights etc. Discuss at least two issues or events we studied this week and explain how they have impacted and/or continue to impact your life today.

BONUS (up to 3 points). Why was the U.S. so much slower than Europe to create a massive, modern military after the Civil War?

The most important foreign action by the U.S. between the Civil War and WWI was the Spanish-American War. This conflict established patterns for future American foreign policy.

Taking Cuba, American imperialists argued, would establish the U.S. as an imperial power, albeit a minor one. The U.S. was not yet a superpower. Five European nations had just finished dividing the African continent in five, separate colonies. Europe was also colonizing Asia and parts of the Middle East. A new generation of politicians, best exemplified by Pres. Theodore Roosevelt, demanded that the U.S. government start expanding their own empire.

Cuba remains central to U.S. foreign policy through today.

Why was Cuba so important?

Cuba was geographically close to the U.S., a ferry ride less than an hour from Florida.

Money. Cuba had the potential to make American companies unbelievably wealthy. Cuba had acre after acre of sugar plantations. Who cares?

In 1900, the average American ate less than eight (8) ounces of sugar annually.

In 1959, Americans ate over six (6) pounds of sugar, mostly from Cuba.

Americans had economically developed and industrialized significantly by 1898.

What did Americans want to develop further?

Cheap raw materials

Foreign markets for American manufactured goods
After T. Roosevelt (helped to) create the Panama Canal, T. America’s economic strength exploded internationally.

D. Proving America’s Early Military Power Internationally.

America’s military was comparatively weak, even after WWI. In the late 1930s, for example, the League of Nations ranked the U.S. military as the 19th strongest in the world. (We were rated after Belgium and the Netherlands, for instance).

Political Generational Differences. Younger, post-Civil War politicians like T.R. desperately wanted war. The older generation of politicians, like Pres. McKinley, remembered the Civil War violence. War did not seem glamorous them.

The younger generation wanted to compete with Europe in colonization and military strength.

E. The First “Sin City”

The Italian Mafia invested early in Cuba, creating complicated and wealthy networks of prostitution, gambling, lavish hotels like the Tropicana Hotel, and all kinds of pornography after 1921. It was the first Vegas.

Cuba was not an American colony; therefore, was not under U.S. “sin” laws.

F. Government claims of foreign terrorism used to justify war.

When the U.S.S. Maine exploded in Cuban waters, the U.S. government blamed foreign terrorism and justified military action. While the explosion was terrifyingly real, terrorism was not the cause.

G. The Yellow Press

THE SPANISH-AMERCAN WAR WAS THE FIRST FOREIGN CONFLICT WHICH WAS FUNDAMENTALLY AND INTENTIONALLY INFLUENCED BY THE MEDIA. I AM REFERRING SPECIFICALLY TO THE MAIN OWNERS OF THE YELLOW PRESS, WILLIAM RANDOLPH HEARST AND JOSEPH PULITIZER.

Like today, most Americans were dependent on media coverage for knowledge of foreign affairs. No one knew what was actually happening Cuba. The yellow press and politicians like T. Roosevelt said the Cubans wanted the U.S. to go to war with the Spanish. Hearst and Pulitzer spend weeks telling Americans that Cubans were being murdered, attacked and raped by Spaniards. (We know now that this was far from true) “Serious” newspapers and moderate politicians argued that most Cubans had no problem with the Spanish government. No one really knew which politician and media source was telling the truth.
