The following statements relate to a laminar flow :
1. Laminar flow is rotational.
2. In laminar flow the loss of head is proportional to the square of the velocity.
3. In laminar flow the loss of head is proportional to the first power of viscosity.
4. In laminar flow the velocity is constant over the cross-section.
5. Other quantities remaining the same, increase in diameter will increase the Reynolds number in laminar flow.

In the figure shows two blocks of equal weights designated as W1 and W2 connected together by a rod and resting on an inclined plane whose angle α can be varied. The coefficients of friction between the blocks and the surface of the plane are μ1 = 0.2 and μ2 = 0.3. The value of angle α at which the slipping will commence is given by

Consider the following statements :
1. Obtaining reliable properties of soil is very important in geotechnical engineering. Chunk
samples obtained from the field are the best for this purpose.
2. Chunk samples may easily be obtained at all depths below ground level and for all types of soils.
3. Undisturbed soil samples are enclosed in rugged containers. As such, they do not get disturbed easily during transportation and handling.
