PHXI10:MECHANICAL PROPERTIES OF FLUIDS

361373 Three horizontal capillary tubes of same radii and lengths \({L_1},\;{L_2}\) and \({L_3}\) are fitted side by side to the wall of a tank that is filled with water. The length of a single capillary tube of same radius that can replace the three tubes such that the rate of flow of water through the single tube equals the combined rate of flow through the three tubes is

1 \(\dfrac{L_{1} L_{2} L_{3}}{L_{1}+L_{2}+L_{3}}\)
2 \(\dfrac{L_{1} L_{2} L_{3}}{L_{1} L_{2}+L_{2} L_{3}+L_{3} L_{1}}\)
3 \(\dfrac{L_{1}+L_{2}+L_{3}}{L_{1} L_{2} L_{3}}\)
4 \(\dfrac{L_{1} L_{2}+L_{2} L_{3}+L_{3} L_{1}}{L_{1} L_{2} L_{3}}\)

361375 Assertion :
The velocity of fall of a man jumping with a parachute first increases and then becomes constant.
Reason :
The constant velocity of fall of man is called terminal velocity.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
