Part II. Longer problem focused on problem solving multiple steps. This problem will be graded based on process, clarity of work, and correct answer and units. a. A spring is stretched, with a force, F = 442 lbf, along the outside of a pipe as shown with a = 53° and ẞ 69° and the coordinates of the force are (15,37,-71 ). How far does the spring stretch if the spring constant is k=67 lb/in? Hint: The force that stretches the spring is the projected force along the pipe F (x, y, z)

Problem 2 An Air Force Research Lab engineer is asked to evaluate the maximum theoretical work that could be produced by the first stage turbine section of an experimental jet engine. Test stand measurements provide the following information: a. Entering air conditions: 1400 K, 8 bar b. Exiting air conditions: .8 bar Part 1: Since you don't have a mass flow rate measurement, what will be the units will you report maximum theoretical work in? Part 2: Write the first law equation for your control volume showing all terms. What assumptions will you make to simplify the equation. Part 3: Pin down the outlet state on a notional T-s diagram for air (just show the two isobars). Why did you select this point? Part 4: What assumption about the properties of air will you make in order to solve this problem? Part 5: Use the appropriate form of the 'Tds' equation and the air tables to solve for the exit state. Part 6: Calculate the max theoretical work

15. Statements Which of these statements are correct? (Note: multiple answers possible) U Water vaporizes at 100 [OC], it cannot evaporate into room air Water droplets can evaporate into air because of their low partial pressure Water droplets can evaporate into air because of their high partial pressure When spraying water droplets into air, the temperature of the air decreases The cooling effect of spraying droplets in very humid air (close to saturation) is much lower than spraying droplets in dry air Pump energy for spraying water is high and evaporative cooling is therefore not efficient

PLEASE INDICATE THE UNITS

Water in the liquid state has the highest temperature. Select one: True False

Question 1) Calculate how much energy (J) is required to heat up a pot containing 500. g of water from 23.0 °C to its boiling point of 100.0 °C (specific heat of water = 4.184 J/g°C). Question 2) An unknown solid object with a mass of 35.0 g was heated to 100.0 °C and transferred to a calorimeter containing 50.0 g of water at 23.0 °C. After thermal equilibrium was reached, the temperature inside the calorimeter was 26.5 °C. Calculate the specific heat of the unknown solid (specific heat of water = 4.184 J/g°C).

Task 1 You are a student at the HTU University, the instructor of the fundamental of thermodynamic course asked you to explain the fundamentals of thermodynamic systems to Grade 10 school students to help them visualize the importance of thermodynamics in their life starting from their car engine and moving to the different appliance that they use in their home, discuss the following with school students: Q1. What does thermodynamics mean and represent? Give examples from your daily life. Q2. What is a thermodynamic property? What is the difference between intensive and extensive properties. Why the density is an intensive property; it is dependent on mass and volume which are extensive properties, right?. Q3. What is the difference between energy and heat transfer? Give examples on both. Q4. What does the first law of thermodynamics state? Give two examples on the first law of thermodynamics from your daily life. Q5. Write down the equation of energy balance for closed, open, and…

bliuzodt to mopolb 9. If machine parts are degreased by means of kerosene as shown in the diagram, how much kerosene make-up is needed per day? How much kerosene has to enter the degreasing vat per day? There are about 3 lb of grease per 100 lb of machine parts, and 60 tons of machine parts are processed each day. Five thousand pounds of kerosene (the 10% solution) are carried away by the machine parts each day but drip off and are caught and put back in the degreasing vat. Two hundred pounds of the 10% solution are lost each day from the vat by evaporation, spillage, or by being carried away.
