- 16. Your supervisor has assigned you the task of designing a set of measuring spoons with a "futuristic" shape. After considerable effort, you have come up with two geometric shapes that you believe are really interesting.
You make prototypes of five spoons for each shape with different depths and measure the volume each will hold. The following table shows the data you collected.
Depth (d) [cm] | Volume (VA) [mL] Shape A | Volume (VB [ml] Shape B |
0.5 | 1 | 1.2 |
0.9 | 2.5 | 3.3 |
1.3 | 4 | 6.4 |
1.4 | 5 | 7.7 |
1.7 | 7 | 11 |
Use Excel to plot and determine appropriate power models for this data. Use the resulting models to determine the depths of a set of measuring spoons comprising the following volumes for each of the two designs:
Volume Needed (V) [tsp or tbsp] |
Depth of Design A (dA) [cm] |
Depth of Design B (dg [cm] |
¼ tsp | ||
½ tsp | ||
¾ tsp | ||
1 tsp | ||
1 tsp |

- Seawater can be purified by distillation into potable water. If it costs 15 cents per kilowatt-hour for energy, what is the cost of energy to produce 100.0 gallons of drinking water at 100.0 ˚C if the seawater starts at 25.00 ˚C? (1 watt × 1 second = 1 joule). Enter your answer to the nearest penny.arrow_forwardafter solving, pls explain why u got the answer really need an explanation thank u so much pls explain in sentences. will ratearrow_forwardHi. I am trying to practice this problem using a checker online, but everytime I recalculate my answer it always says it's incorrect. So far I have calculated and tried to input the following values: 0.0342 m3/s, 0.0358 m3/s, 0.04277 m3/s, and 0.0555 m3/s but it always keeps saying they are incorrect. Please help show me the correct steps on how to get the correct answer as I am trying to learn this process. Thank you!arrow_forward
- Learning Goal: To use equilibrium to calculate the plane state of stress in a rotated coordinate system. In general, the three-dimensional state of stress at a point requires six stress components to be fully described: three normal stresses and three shear stresses (Figure 1). When the external loadings are coplanar, however, the resulting internal stresses can be treated as plane stress and described using a simpler, two-dimensional analysis with just two normal stresses and one shear stress (Figure 2). The third normal stress and two other shear stresses are assumed to be zero. The normal and shear stresses for a state of stress depend on the orientation of the axes. If the stresses are given in one coordinate system (Figure 3), the equivalent stresses in a rotated coordinate system (Figure 4) can be calculated using the equations of static equilibrium. Both sets of stresses describe the same state of stress. The stresses σx′and τx′y′ can be found by considering the free-body…arrow_forwardPlease provide equations that you are using so I can follow along and learn how to do this and include conversions and units. In Jamestown, NY, a coal power plan consumes coal at a rate of 80 tons/hr. When coal burns, it generates approximately 30,000 kJ for every kg of coal burned. The cooling course for the plant is the nearby Chadakoin River nearby and, by code, the power plant cannot reject more than 13.19 x 109 MJ into the river annually. Determine the maximum average power output of this plant and it's maximum thermal efficiency. To check your work, enter the efficiency, as a decimal, in the box provided.arrow_forwardUsing graphical method solve this problem: Suppose you first walk A in a direction of B west of north then C in a direction D south of west. You rest for 20 minutes and started to compute the distance you traveled. Take A, B, C and D found in the table below. (You may use scale such as 1cm = 2m in your drawing) C. What is the angle between AC ? D. What is the angle between your first walk A to the resultant R?arrow_forward
