II Question 2 A process instrument reading Z (volts) is thought to be related to a process stream flow rate V (L/s) and pressure P (kPa) by the expression: Z = aVÞp°. Using the three data points shown in the table above, calculate the constants a, b and c and indicate their units. In this particular case there is no regression to be performed, but only 3 equations in 3 unknowns to solve. 1 1.02 V (L/s) P (kPa) z (volts) 1.20 1.75 11.2 10.2 9.1 2.58 3.72 3.50 ere to search 12
3. Examine your data in Data Table 2 and in Data Table 3. For the data with the smallest percentage difference, compare the total energy at each point. Calculate the sum U₁+Ug at x₁ as ½kx-mgx₁. Calculate that sum at x₂ as ½kx²-mgx₂. Do you expect them to agree reasonably well? Explain why they should or should not be the same. 4. Consider the same data as used in Question 3. Calculate the value of x halfway between x₁ and x₂. Calculate U₁+Ug=½kx² − mgx_for_that point. Do you expect them to agree with the energy calculated in Question 3? If they agree reasonably well, explain why they do. If they do not agree, explain why they do not agree.
