please Solve the three questions for group 2

Question No.1: (5.0 points) The theological behavior of a viscoelastic fluid is emulated by Casson model. The shear stress changes from tyto Ty when the shear rate changes from zero to y. Determine the following: A. The value of Casson yield stress. [1.0 point] B. The value of Casson plastic viscosity. [1.5 point] C. By taking x = 7, express the general quadratic model to calculate the shear stress if the shear rate is known. (2.5 point) Each group is assigned to use the following parameters: Group 1 Group 2 Group 3 Group 4 Group 5 Tu (Pa) 0.4 T2 (Pa) 1.5 # [1] 100 0.45 2.0 125 0.5 2.5 150 0.6 3.0 175 0.65 3.5 200 Question No.3: (2.5 points) Gambill (1959) proposed the following equation for estimating the kinematic viscosity (v) of a two liquid mixture: v1/3 = xavd + xov where (va, vs} and (xa, xy) are the kinematic viscosities and mass fractions of liquid a and liquid b, respectively. The total mass of the mixture is me and the mass of liquid bis m2. If va = y v and v = y v, what is the value of ya? Each group is assigned to use the following parameters: Group 1 Group 2 Group 3 m, [kg] 30 45 25 my [kg] 12 20 60 Group 4 40 30 35 Group 5 57 32 85 15 45 70 Question No.4: (2.5 points) Consider the dynamic viscosities of air (Hair) and carbon dioxide (sco). The air is maintained at temperature Tair. Calculate the temperature of carbon dioxide, Too, when both viscosities are equal (i.e., Hair = Pco,). Express the temperature in deg C. Each group is assigned to use the following parameters: Group 1 Group 2 Group 3 Tair [C] 20 40 35 Group 4 30 Group 5 25
