Question 1 10 Points An impeller (axial-flow turbine propeller) in an agitated tank has an output torque (T) whose dimension is ML2/T2 which is proportional to the volumetric flow rate (Q) and also depends upon the density (p), rotor diameter (D), and rotation rate (N). Perform Dimensional Analysis. Use the editor to format your answer Question 2 10 Points Compute the steady-state momentum flux of pure ethanol at 25C and 1 atm when the lower plate velocity (V) as shown in the figure below is 0.30 meter per second in the positive "x" direction, the plate separation y is 0.305 mm. ... Large Final velocity distribution in steady flow An oil film drains steadily down the side of a vertical wall, as shown on figure below. After an initial development at the top of the wall it attains a fully-developed draining vertical oil- film wherein the film becomes independent of "z" and of constant wall thickness. Let the vertical velocity as (w) and using the nomenclatures in the figure such as distance from plate (x), fluid properties, gravity (g) and film thickness ( 8 ). Oil film L. 1 Let the vertical velocity as (w) and using the nomenclatures in the figure such as distance from plate (x), fluid properties, gravity (g) and film thickness ( ). Oil film Air P, u W Z X Perform dimensional analysis and determine the function in terms of dimensionless parameters
