Answer: A leak in the system
Explanation:
A cylinder of 100 mm diameter and 300 mm
length rotates about a vertical axis inside a
fixed cylindrical tube of 105 mm diameter and
300 mm length. If the space between the tube
and the cylinder is filled with liquid of dynamic
viscosity of 0.125 N.s/mº, determine the speed
of rotation of the cylinder which will be obtained
if an external torque of 1 Nm is applied to it

Actualmente estoy trabajando en una pregunta diferente en este momento.
Explanation:
For the velocity fields given below, determine:
a) whether the flow field is one-, two-, or three-dimensional,
b) whether the flow is steady or unsteady, and why. (The quantities a and b are constants.)
1. V = [ay2e−bt]i
2. V = ax^2i + bxj + ck
3. V = axyi - bytj
4. V = axi - byj + ctk
Answer and Explanation: A fluid flow is steady when its properties (velocity, pressure and others) do not change over time: P = P(x,y,z), with P being any of the properties.
So, an unsteady flow does depend upon time: P = P(x,y,z,t).
1. V = [[tex]ay2e^{-bt}[/tex]]i : This velocity field is one-dimension, because there is only the component in the x-direction and unsteady, because it is dependent upon the variable time (t);
2. V = [tex]ax^{2}i+bxj+ck[/tex] : is a three-dimensional field, because there is one component for each direction (x, y and z) and is steady, since it's independent of time;
3. V = axyi - bytj : is a 2-dimensional field, and since it changes with time, it is unsteady;
4. V = axi - byj + ctk : is a 3-dimensional field and the flow is unsteady;
