Question
With referencing the figure. answer the following statements with Hue or lake and correct the false ones: A) Pressures at A, B, C, and D are equal. B) Pressure D is the greatest. C) Pressure A is smaller than pressure C. D) Pressure B is the smallest. E) At level x-x. pressure at any point is the same F) Relation between B and C is undetermined Using the shell momentum balance approach and applying the power- law model, prove that the velocity profile for a non-Newtonian fluid is: The pipe function factor for a turbulent flow, f, was found to be a function of the pipe diameter. D. and roughness, r; the fluid density, r, and viscosity, mu and the fluid velocity, v, By dimensional analysis, form the dimensionless groups from the variables given. A) Calculate the effective mean diameter? B) Calculate the superficial velocity?Explanation / Answer
1. Options A) and F) are false. Pressures at the bases of containers containing different liquid are not same. Relation between B and C can be easily determined or guessed as they contain an oil and water, which have different density and height.
Further, we know that P2 - P1 = gh = mgh/V
The pressure on the exposed surface of the liquid or static liquid is same in all vessels. Therefore E) is correct.
The pressure on the base, P2 = Patm + gh
As different volume of the same liquid are poured in the vessels A and C, height of liquid is be more in vessel C. Therefore, the pressure on the base of vessel C is more i.e., the option C) and D) are also correct.
Further, Specific Weight of mercury is the manifold greater than oil and water, despite height being smaller the pressure on the base of D is the maximum. Hence, B) is also correct.
