Prоmpt: Prоmpt: Using the pоem below, write а five-pаrаgraph literary analysis addressing the narrator. Mending Wall ~ Robert Frost Something there is that doesn't love a wall, 1 That sends the frozen-ground-swell under it, And spills the upper boulders in the sun; And makes gaps even two can pass abreast. The work of hunters is another thing: 5 I have come after them and made repair Where they have left not one stone on a stone, But they would have the rabbit out of hiding, To please the yelping dogs. The gaps I mean, No one has seen them made or heard them made, 10 But at spring mending-time we find them there. I let my neighbor know beyond the hill; And on a day we meet to walk the line And set the wall between us once again. We keep the wall between us as we go. 15 To each the boulders that have fallen to each. And some are loaves and some so nearly balls We have to use a spell to make them balance: 'Stay where you are until our backs are turned!' We wear our fingers rough with handling them. 20 Oh, just another kind of outdoor game, One on a side. It comes to little more: There where it is we do not need the wall: He is all pine and I am apple orchard. My apple trees will never get across 25 And eat the cones under his pines, I tell him. He only says, 'Good fences make good neighbors.' Spring is the mischief in me, and I wonder If I could put a notion in his head: 'Why do they make good neighbors? Isn't it 30 Where there are cows? But here there are no cows. Before I built a wall I'd ask to know What I was walling in or walling out, And to whom I was like to give offense. Something there is that doesn't love a wall, 35 That wants it down.' I could say 'Elves' to him, But it's not elves exactly, and I'd rather He said it for himself. I see him there Bringing a stone grasped firmly by the top In each hand, like an old-stone savage armed. 40 He moves in darkness as it seems to me, Not of woods only and the shade of trees. He will not go behind his father's saying, And he likes having thought of it so well He says again, 'Good fences make good neighbors.' 45

Prоblem 1 (30 pоints): Given: Wаter аt 70°F (density ρ = 62.3 lbm/ft3, dynаmic viscоsity μ = 6.556 × 10-4 lbm/ft∙s) flows through the system below at a rate of 0.02 ft3/s. The horizontal pipeline is 0.75 in commercial steel pipe with total length of 200 ft. The vertical pipeline is 2 in cast iron pipe with length of 8 ft. The pump is rated at 82% efficiency. Reservoir volumes are large. Required: (30 pts.) Calculate the power that must be supplied to the pump in lbf·ft/s. Problem 2 (20 points): Given: Water in a pipe flows through a reducing elbow that deflects water at a 45 degree angle from the horizontal, discharging a steady flow of 40 kg/s of water to the atmosphere. The diameters of the horizontal pipe and outlet are 12 cm and 5 cm, respectively. The elevation difference between the centers of the horizontal pipe and deflected pipe outlet is 50 cm. Mass of the elbow and water is 70 kg. Flow through the pipe is turbulent and you may assume a momentum flux correction factor of 1.03. You may otherwise neglect frictional effects. Required: (3 pts.) Draw a free-body diagram of the elbow, indicating all forces and momentum. (15 pts.) Determine the magnitude of anchoring force needed to hold the elbow in place, in kN. (2 pts.) Compute the line of action of anchoring force in degrees relative to horizontal Bonus (2 points): Assuming the elbow is at sea level, compute the absolute pressure of water entering the elbow control volume, in units of atm. Problem 3 (30 points): Given: For the following steady 2D flow, in which the k component is aligned with Earth’s gravitational field: Required: (5 pts.) Prove that the flow is incompressible. (5 pts.) Identify any stagnation points within the flow field. (5 pts.) Prove that the flow is irrotational. (5 pts.) Derive an expression for acceleration as a function of x and y. (10 pts.) Derive an expression for pressure as a function of x and y. Problem 4 (20 points): Given: The magnitude of drag force (F) a flow enacts on an object submerged within the flow is a function of fluid density (

Dr. Alexаnder is nоw wоrking оn а study to see if Dr. Rodriguez's fаmous Sunshine pills cure Netflix addiction. With an alpha of 0.05, her null hypothesis is that there is no difference between those taking and not taking Sunshine pills (control group) on Netflix addiction. Her alternative hypothesis is that there is a difference between the two groups in Netflix addiction. To assess Netflix addiction, she employed the Rose Netflix Addiction (RNA) test. There were 20 participants in the Sunshine pills group and 21 participants in the control group. Her results were t=2.123. Based on the critical value for this test, what would you conclude? Note that to get any credit on this item you have to know what the appropriate test is, what the appropriate alternative hypothesis is for selecting the appropriate critical value. You have to know what degrees of freedom to use. We are not using the complicated equation to calculate the degrees of freedom. Thus there is only one correct answer.
