On a flow net diagram, the distance between two consecutive steam lines at two successive sections are 1 cm and 0.5 cm respectively. If the velocity at the first section is 1 m/sec, the velocity at the second is
-
If L, D and f are the length, diameter and coefficient of friction of a pipe, the ratio of the areas of the pipe A and nozzle a, to transmit maximum power, is
-
The flow is called rotational if its velocity normal to the plane of area is equal to
