1.Turpentine oil is flowing through a tube of length l and radius r. The pressure difference between the two ends of the tube is P. The viscosity of the oil is given by
π=π(π2β π₯2)/4π£π
Where v is the velocity of oil at a distance x from the axis of the tube. Determine the dimensions of Ξ·.
2. The position x of a particle depends upon time t according to the equation x = at + bt2. Determine the dimensions and units of a and b. What are the physical quantities denoted by a and b?
3. The velocity v of a particle depends upon time t according to the relation
π£=ππ‘+ π/π‘+π
What are the dimensions of a, b and c?
1 We have:
2 The physical quantities denoted by a and b are initial velocity and acceleration: x is in meters, so
3 Same approach as in (2):
