For each problem, sketch the appropriate process diagram on a T-v, P-v, or P-h diagram

4.60 : Steam exiting the turbine of a power plant passes through the insulated shell-and-tube heat exchanger condenser. The mass flow rate of the steam is 145 kg/s, and the steam enters the heat exchanger as a saturated mixture with a quality of 0.95 at 20 kPa. The steam exits the condenser as a saturated liquid at 20 kPa. Liquid cooling water is used to condense the steam. The cooling water enters the condenser at 10 degrees celsius. (a) Determine the exit temperature of the liquid cooling water if the mass flow rate is 4000 kg/s. (b) Using your heat exchanger model, plot the cooling water mass flow rate and volumetric flow rate (entering the condenser) for exit temperatures ranging from 15 degrees celsius to 55 degrees celsius. (c) if the exit temperature of the cooling water is regulated such that it must be no greater than 40 degrees celsius, and if the cooling water flow rate through the condenser can be adjusted in a range from 500 kg/s to 2000 kg/s, what is the range of maximum possible flow rates of steam through the condenser?

Victoria and Vine (V&V) has 1 million shares outstanding, selling at $20/share. To finance the expansion of their winery business V&V is planning a rights offering, allowing one new share to be purchased for each 10 shares currently held. The purchase price (subscription price) will be $14.50 a share.

a)How many shares will be issued? (1 Mark)

b)How much money will be raised? (1 mark)

c)What will the stock price be after rights issue (ex-rights)?

d)What action(s) would you have to take in the rights offering if you wanted to maintain your ownership? No Calculations required. (1 Mark)

Problem 2. Consider a graph G = (V,E) where |V|=n.

2(a) What is the total number of possible paths of length k ≥ 0 in G from a given starting vertex s and ending vertex t? Hint: a path of length k is a sequence of k + 1 vertices without duplicates.

2(b) What is the total number of possible paths of any length in G from a given starting vertex s and ending vertex t?

2(c) What is the total number of possible cycles of any length in G from a given starting vertex s?

Upriver Parts manufactures two products, V-1 and V-2, at its River Plant. Selected data for an average month for the two products follow. V-1 V-2 Units produced 10,000 1,000 Direct materials cost per unit $ 2 $ 4 Machine hours per unit 1 2 Production runs per month 80 40 Production at the plant is automated and any labor cost is included in overhead. Data on manufacturing overhead at the plant follow. Machine depreciation $ 36,000 Setup labor 18,000 Material handling 14,400 Total $ 68,400 Required: a. Upriver currently applies overhead on the basis of machine hours. What is the predetermined overhead rate for the month? (Round your answer to 2 decimal places.) b. Upriver is thinking of adopting an ABC system. They have tentatively chosen the following cost drivers: machine hours for machine depreciation, production runs for setup labor, and direct material dollars for material handling. Compute the cost driver rates for the proposed system at Upriver.

Given: M1= 75kg; M2 = 50kg; V (M1) = 10 m/s North; V (M2) = 10 m/s West

Action: Collision, two masses stick together, move at unspecified angle in M2's initial direction

Question: Find magnitude of their speed together after collision.

Your protocols call for a dopamine infusion beginning at 5 micrograms per kilogram per minute. You estimate that your patient weighs 190 pounds. Using a standard dopamine concentration of 800 mg in 500 mL, at what drip rate (in drops/minute) will you need to administer the infusion using micro-drip tubing?   

1. E. coli DNA polymerase V has the ability to bypass thymine dimers. However, Pol V tends to incorporate G rather than A opposite the dam-aged T bases. Would you expect Pol V to be more or less processive than Pol III? Explain.

2. Explain why base excision repair, nucleotide excision repair, and mismatch repair—which all require nucleases to excise damaged DNA—require DNA ligase.

3. Why are there no Pol I mutants that completely lack 5′ → 3′ exo-nuclease activity?

What resources should be utilize when creating assessments to meet diverse students' needs in addition to accommodations? With whom might you make contact in order to obtain further information about students' needs? For example, this may refer to ELL students or students with IEPs

A student surveys some students on campus in the evening and finds that 16 out of 20 of the students she interviewed are part time students. She uses the data to estimate the percentage of all students who are part time. What type of bias is present in her sample?
