It is desired to produce liquefied natural gas (LNG), which we consider to be pure methane, from that gas at 1 bar and 280 K (conditions “1” in the Linde process of the diagram). Leaving the cooler (“enfriador”) methane is at 100 bar and 210 K. The flash drum (“separador”) is adiabatic and operates at 1 bar. The recycled methane leaving the heat exchanger is at 1 bar and 200 K. The compressor can be assumed to operate reversibly and adiabatically. However, because of the large pressure change, a three-stage compressor with intercooling is used. The first stage compresses the gas from 1 bar to 5 bar, the second stage from 5 bar to 25 bar, and the third stage from 25 bar to 100 bar. Between stages the gas is isobarically cooled to 280 K.

(a)For each point in the Linde diagram write the conditions you know, and find the corresponding points in the H-P diagram for methane.

(b)Calculate the fractions of vapor and liquid leaving the flash drum.

(c)Calculate the amount of compressor work required for each kg of LNG produced.

GREEN NEW DEAL

1.This deal states that we need to be net-zero global emissions by 2050. You saw a graphic on class Monday, showing how the U.S. could be 100% renewable by 2050. What is the biggest challenge you see to applying this on a global scale?

2.. I read Fox News’ assessment of the Green New Deal. They said if we make the switch to 100% renewables, it would result in the BIRD-pocylypse: “untold millions of birds being slaughtered by Democrats’ supposedly ‘environmentally friendly’ green energy sources, including wind farms and solar energy facilities.” Do you agree or disagree with this retort? Explain your position here

3.. The latest science says we have just 12 years to complete the energy and economic overhaul necessary to limit warming to a manageable level and avoid the worst consequences. These are HUGE goals, perhaps not accomplishable in our lifetimes, BUT we can take baby steps, right? Which “baby step” do you think should be addressed first – and how?

A book publisher knows that it takes an average of nine business days from when the material for the book is finalized until the first edition is printed and ready to sell. Suppose the exact amount of time has a standard deviation of four days. Use an appropriate normal transformation to answer the following questions. a. Suppose the publisher examines the printing time for a sample of 36 books. What is the probability that the sample mean time is shorter than eight days? 0.0668 b. Suppose the publisher examines the printing time for a sample of 36 books. What is the probability that the sample mean time is between 7 and 10 days? 0.9973 c. Suppose the publisher signs a contract for the printer to print 100 books. If the average printing time for the 100 books is longer than 9.3 days, the printer must pay a penalty. What is the probability the penalty clause will be activated? 0.2266 d. Suppose the publisher signs a contract for the printer to print 10 books. If the average printing time for the 10 books is longer than 9.7 days, the printer must pay a penalty. What is the probability the penalty clause will be activated?

Hanson Company has an inexperienced accountant. During the first month on the job, the accountant made the following errors in journalizing transactions. All entries were posted as made.

1. The purchase of store supplies on account for $1,510 was recorded as a debit to Supplies $1,150 and a credit to Accounts Payable $1,150.
2. The purchase of office supplies for $650 cash was debited to Equipment $210 and credited to Cash $210.
3. A $500 withdrawal of cash for B. Hanson’s personal use was debited to Salaries and Wages Expense $900 and credited to Cash $900.
4. A payment on account of $820 to a creditor was debited to Accounts Payable $280 and credited to Cash $280.
5. A payment of Salaries and Wages Expense of $700 was debited to Equipment and credited to Cash, both for $700.
6. A collection of $1,000 from a client on account was debited to Cash $100 and credited to Service Revenue $100.
7. The purchase of equipment on account for $760 was debited to Equipment $670 and credited to Accounts Payable $670.

Instructions

(a) Correct the errors by reversing the incorrect entry and preparing the correct entry.

(b) Correct the errors without reversing the incorrect entry.

Adam, Beth, Clayton and David are forming a bakery business, called ABCD Corp, and decided to organize as a corporation. Adam Beth and Clayton will each own 300 shares of the common stock and David will own 100 shares of the stock (there are 1000 shares total of the corporation). Adam is contributing cash of $200,000, Beth is contributing equipment from a prior business that was originally purchased for $300,000 and was depreciated for tax purposes by $120,000 (current FMV is $200,000). Clayton is contributing a store front that he purchased two years ago for $250,000, but is currently worth only $200,000. David is contributing his time and will work full time for the business as the manager for the first year to train all the staff and get the business running on its own (David’s services would cost $67,000).

E. What would be the result if two years after formation, a capital call is made and each shareholder is required to contribute $100 of cash for each share owned? What if Beth wanted to meet the capital call with appreciated property?

I gave full question

Density is a physical property which plays a very important role in our daily life. It is very widely used in all field of engineering. Density is widely used for choosing the suitability of a material for a specific purpose.

a) Discuss how density is finding its application in Marine engineering field in not more than 100 to 150 words.
b) Describe the way in which you can determine the density of given substances. Also explain the tools which are used for finding the density. Explain in detail.
c) You are given a cylindrical shaped silver having diameter X cm and height Y cm.
[ You can take X – the first two digits of your student ID and Y – the last two digits of your student ID. For e.g., If the student’s ID is 1875-18, The X = 18 and Y = 75]. The density of silver is 10.5 g/cm3. Calculate the mass of the silver shape given to you in kg/m3.
[ for conversion you can use - 1 m = 100 cm and 1 kg = 1000 g]

Your company wants to take advantage of the growing Asian market and plans to build a manufacturing facility in the southeast region to support the expansion. Management identified a set of critical factors to evaluate the prospective location, as shown in the table below; they used a rating system of 1 (least desirable) to 100 (most desirable) to evaluate each factor.

First, identify which location you would recommend based on the current scores shown in the table.

If political unrest broke out in Singapore, lowering the political risk score for that location to 30, would this change your original conclusion? Indicate your original and updated recommendation, respectively, based exclusively on the multi-criteria scores.

Problem 3 Write code in R or Rstudio (Programming)

A prime number is an integer greater than one whose only factors are one and itself. For example, the first ten prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29. A twin prime is a prime that has a prime gap of two. Sometimes the term twin prime is used for a pair of twin primes. For example, the five twin prime pairs are (3, 5), (5, 7), (11, 13), (17, 19) and (29, 31). (a) Write a function that returns all prime numbers between 1 and a given number n Answer: (b) How many prime numbers are there in the range [1, 100], [1, 1000] and [1, 10000] (c) How many twin prime pairs are there in the range [1, 100], [1, 1000] and [1, 10000] (d) In number theory, the prime number theorem (PNT) indicates that for a large enough n, the number of primes in the range [1, n] approximates to n/log(n). Please verify it by trying wider range.
