The density of water is 103kg/m3. The water pressure on a submarine is 2.0 x 107N/m2. The depth of the submarine below the surface of the water, in maters, is approximately
A tube is tapered from 20 cm diameter to 2 cm diameter, the velocity at the first cross-section is 50 cm/s, then the velocity at the second cross-section is
If every particle of the flow that passes a particular point, moves along the same path as followed by particles which passed the point earlier, then this flow is said to be
If water rises 4 cm in a long, thin tube because of capillary action, then, under corresponding conditions of use, the rise (in the tube) of a liquid whose density is 2 g/cm2will be
The drag force acting on a spherical droplet of radius 10-5m moving with a velocity of 1 cm/sec in a fluid of velocity 5.31 x 10-7m/sec. The units comes out to be:
