Solve the system. If the system has one unique solution, write the solution set. Otherwise, determine the number of solutions to the system, and determine whether the system is inconsistent, or the equations are dependent. $3x - 5y - 3z = 46$ $5x + y - 9z = 42$ $-4x + 6y + 3z = -55$ The system has one solution. The solution set is {$\Box$} The system has no solution. The system is inconsistent. The equations are dependent. The system has infinitely many solutions. The system is inconsistent. The equations are dependent.

CSM2178 Fluid Mechanics (a) (i) How does the Reynolds number represent a ratio between forces in fluid flows? Re, Fr (1 mark) (ii) Explain how dimensionless ratios are used to relate results from scaled models to full scale systems. (iii) Briefly explain (with the support of examples) what is meant by incomplete similarity or scale effects? Are they different? (b) For fluids flowing in pipes, the shear stress at the wall τw is almost impossible to measure directly. From a series of experiments it was found that τw is dependent on a number of physical parameters: τw = φ(ρ, u, d, μ) where ρ is the density of the fluid, u is the mean velocity of flow, d is the diameter of the pipe, μ is the dynamic viscosity and φ is an unknown function. Use the Buckingham Pi theorem to identify relevant dimensionless ratios for the situation described above. (c) Tests on the established flow of six different liquids in smooth pipes of various sizes yields the following data: Diameter(m) Velocity(m/s) Viscosity(Pa.s) Density(kg/m^3) Wall Shear(Pa) 0.30 2.26 0.862 1247 51.2 0.25 2.47 0.431 1031 33.5 0.15 1.22 0.0843 907 5.41 0.10 1.39 0.0440 938 9.67 0.05 0.20 0.0015 861 0.162 0.03 0.36 0.001 1000 0.517 Table Q1.1 You will use this data to investigate the following relationship: f((τw)/(ρu^2), (ρud)/(μ)) = 0 (i) Calculate the values for the two dimensionless ratios in the above relationship for each row in table Q1.1. Show your results in table form. (2 marks) (ii) Plot the relevant dimensionless numbers on an appropriate axis with due consideration for appropriate graph plotting conventions.

Researchers had participants review feedback from their teacher on a final paper. After reading the feedback, participants rated the teacher's comment on how fair and legitimate they thought the comment was. Participants also rated their overall impression of their teacher. The research team ran a regression to see if fairness and legitimate ratings predict overall teacher impression. Below is the output for their regression analysis. Regression a. Dependent Variable: Teacher_Impression b. All requested variables entered. a. Predictors: (Constant), Legitimate_Ratings, Fairness_Ratings Which statement best describes the amount of variance in the criterion variable that is being explained by the predictors? - 66.8% of variance in the criterion variable is being explained by the predictors
