An insulated stream of warm water is produced in a steady flow mixing process by combining 1 kg/s of cold water at 25 oC with 0.8 kg/s of hot water at 75 oC. What is the temperature of warm-water stream ? what is the work of the mixing process, , and ? assume the specific heat of water is constant at 4.18 kJ/kg.K.

enny, Inc., is looking at setting up a new manufacturing plant in South Park. The company bought some land six years ago for $8.1 million in anticipation of using it as a warehouse and distribution site, but the company has since decided to rent facilities elsewhere. The land would net $10.9 million if it were sold today. The company now wants to build its new manufacturing plant on this land; the plant will cost $22.1 million to build, and the site requires $960,000 worth of grading before it is suitable for construction.

What is the proper cash flow amount to use as the initial investment in fixed assets when evaluating this project? (Do not round intermediate calculations and enter your answer in dollars, not millions, rounded to the nearest whole number, e.g., 1,234,567.)

Rangers at the everglades national park, ride an air-boat, the mass of the air boat plus the rangers is 500 kg. The blades of the boat push on the air with 1000N, while moving the rangers experience an air resistance force of 200N directed opposite to the direction of motion, and the boat a water resistance of 250N. They move in straight line for 20s. Please complete the following tasks:

1. Draw the free-body diagram showing all forces acting on the air-boat ranger system.

2. Calculate the net force acting on the boat-ranger system;

3. Determine the accelerations of the air boat system;

4. What is the coefficient of friction between the water and the boat?

5. What is the velocity of the boat at the end of the 20s, if its initial velocity was 20 m/s?

6. How far did the boat travel in those 20s?

Parker & Stone, Inc., is looking at setting up a new manufacturing plant in South Park to produce garden tools. The company bought some land six years ago for $5.1 million in anticipation of using it as a warehouse and distribution site, but the company has since decided to rent these facilities from a competitor instead. If the land were sold today, the company would net $5.4 million. The company wants to build its new manufacturing plant on this land; the plant will cost $12.6 million to build, and the site requires $780,000 worth of grading before it is suitable for construction. What is the proper cash flow amount to use as the initial investment in fixed assets when evaluating this project? (Enter your answer as a positive value in dollars, not millions of dollars, e.g., 1,234,567.)

You may need to use the appropriate technology to answer this question.

An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading riders more efficiently. Two alternative loading/unloading methods have been proposed. To account for potential differences due to the type of ride and the possible interaction between the method of loading and unloading and the type of ride, a factorial experiment was designed. Use the following data to test for any significant effect due to the loading and unloading method, the type of ride, and interaction. Use α = 0.05.

Find the value of the test statistic for method of loading and unloading.

Find the p-value for method of loading and unloading. (Round your answer to three decimal places.)

In an amusement park ride, a 4m long lightweight rod connects the center motorized pivot to a car. The motor applies a couple of 30t2 Nm, and another motor in the car generates a forward force F=15t N. The mass of the car and rider is 150 kg. If the car starts from rest,

a. Determine the speed of the car at t = 10 s.

b. At t=10s, the center motor is switched off and spins freely, but the car motor remains engaged. What is the force in the rod.

c. If at t =15s the car motor is also switched off, and brakes are applied that deliver a constant force of 10N, how long does it take for the car to come to rest after the brakes are applied.

How Much of a Major Auto Accident Loss Will Be Covered? Ashley Diamond of Estes Park, Colorado, drives an eight-year-old Toyota valued at $9,900. She has a $70,000 personal automobile policy with $10,000 per-person medical payments coverage and both collision ($200 deductible) and comprehensive coverage. David Smith of Loveland, Colorado, drives a four-year-old Chevrolet Malibu valued at $9,300. He has a 25/50/15 family automobile policy with $18,000 in medical payments coverage and both collision ($100 deductible) and comprehensive insurance. Late one evening, while he was driving back from Rocky Mountain National Park, David's car crossed the centerline of the road, striking Ashley's car and forcing it into a ditch. David's car also left the road and did extensive damage to the front of a roadside store. The following table indicates the damages and their dollar amounts:

Item

Amount Bodily injuries suffered by Ashley $ 6,600

Bodily injuries suffered by Fran, a passenger in Ashley's car 28,517

You are assessing the viability of operating an amusement park. The nominal revenues from ticket sales at the end of Year 1 will be $554176. They will increase by 4% per year in real terms. The only annual cost will be to lease the whole operation for $118845 per year. The leasing costs are nominal and will start at the end of Year 1. They will stay fixed in nominal terms.

Assume the inflation rate is 5% and the real discount rate is 10%. All cash flows occur at year-end. The company will not pay any taxes. The business will continue into perpetuity.

What is the NPV of the project?

6. Caretakers, a local nonprofit organization, operates the concession stands for the Newland Baseball Park, home of the Newland Nuggets (a minor league baseball team). Doing so permits Caretakers to raise funds to operate its soup kitchen. Caretakers is concerned with waste in the concessions area. Too many precooked hot dogs are left over after a game. Heinz Canine, Caretakers’ research analyst, feels that hot dog consumption (and other concession sales) can be predicted by the number of advance sale tickets purchased for a game (attendance is usually twice advance sales). Heinz gathers the accompanying data for a sample of 10 days. Run the regression for Heinz and tell him whether his hypothesis is correct. Predict how many hot dogs will be sold if 1,000 advance tickets are sold.
