List the various types of fluid. Define kinematic viscosity and compressibility. Note the expression of capillary fall

n = Xe()r -------Equation 1 where X = 1.7419 and (E/R) = -0.018 are constants for a given fluid. You are required to carry out appropriate calculations on the effect of changes in temperature given in table A by using equation 1 for Ethanol on the viscosity of a fluid. Table A NO Temperature viscocity n T°C cP 10 3 20 30 5 40 6. 50 7 60 8 70 In addition to this, calculate other constraints such as the variety of shear stress (T) and force due to fluid viscosity, when the two layers of different compressible Newtonian fluids are contained between two flat plates separated by a distance of 0.05m and fluid moving with the velocity of 2m/s in the horizontal direction. Assume the shear area between the fluid layers is 0.5m². To do this you required to explain, with examples, the effects of temperature and shear forces on Newtonian and non-Newtonian fluid. Also, explain the operation and constraints of different viscometers that quantify viscosity in fluids. 2.

Question 1: Define and state the viscosity equation for a Coutte flow. Question 2: Develop and algebraic equation for viscosity of a liquid as a function of temperature. Calculate the kinematic viscosity of water at T = 303 K. Question 3: If a liquid water at 300C is flowing in a pipe and the pressure drops to the vapor pressure, what happens in the water and why, explain?

The device in Fig.  is called a cone-plate viscometer. The angle of the cone is very small, so that sin θ ≈ θ ,and the gap is fi lled with the test liquid. The torque M torotate the cone at a rate V is measured. Assuming a linearvelocity profi le in the fl uid fi lm, derive an expression forfl uid viscosity μ as a function of ( M , R , V , θ ).
