Linear Interpolation Homework Review

1. Estimate the viscosity of water at 55 o F (x1, y1)-->(50, 1.310) (x2, y2)-->(55, ?) (x3, y3)-->(60, 1.129)

3
2. Estimate the viscosity of water at 142 o F (x1, y1)-->(140, 0.470) (x2, y2)-->(142, ?) (x3, y3)-->(160, 0.401)

4
3. What is the difference in viscosity of 155 o F water and 55 o F water?... Know 55 o F is 1.220cP from problem 1 (x1, y1)-->(140, 0.470) (x2, y2)-->(155, ?) (x3, y3)-->(160, 0.401) – = cP

5
4. At what temperature is the viscosity of water 1cP? (x1, y1)-->(1.129, 60) (x2, y2)-->(1, ?) (x3, y3)-->(0.982, 70)

5. Johnny measured the viscosity of his sample to be 1.55cP. What is the likely temperature of his sample? (x1, y1)-->(1.794, 32) (x2, y2)-->(1.55, ?) (x3, y3)-->(1.546, 40)

7
6. What happens to water at 32 o F? Do you expect that to affect the viscosity?

8
7. Use the data points at 180 o F and 200 o F to estimate the viscosity of water at 205 o F. What is the danger of doing this? (x1, y1)-->(180, 0.347) (x2, y2)-->(205, ?) (x3, y3)-->(200, 0.305)
