PHXI10:MECHANICAL PROPERTIES OF FLUIDS

360805 Assertion :
The size of the needle of a syringe controls a flow rate better than the thumb pressure exerted by a doctor while administering an injection.
Reason :
Flow rate is independent of pressure exerted by the thumb of the doctor.

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.

360806 A tap water pipe is bent as shown in the diagram. Sections 1 and 2 of the pipe are horizontal but section 2 is placed higher at a height of \(H\). The diameter of the pipe of section 1 is 1.5 times larger than the diameter of section 2. Indicate which of the following is the most complete answer for relationship between the hydrostatic pressure measured by the gauges in sections 1 and 2 .
supporting img

1 \(P_{1}>P_{2}\) because water flows slower in section 1 , and section 1 is lower than section 2.
2 \(P_{1} < P_{2}\) because water flows lower in section 1.
3 \(P_{1}>P_{2}\) because section 1 is lower than section 2.
4 \(P_{1}>P_{2}\) because water flows slower in section 1.

360807 If air is blown through the space between a calendar suspended from a nail on wall and the wall, then

1 The calendar moves close to the wall.
2 The calendar moves farther from the wall.
3 The position of the calendar does not change.
4 The position of the calendar may or maynot change.

360808 Water is flowing in a canal speed \(v=10 {~m} / {s}\). A bend tube is lowered into the canal as shown in figure. The upper end of the tube is held at a height \(h_{0}=3 {~m}\) above the surface of the water. To what height ' \(h\) ' above the upper end of the tube, will the water jet spurt? Assume that flow remains ideal. (Take \(g=10 {~m} / {s}^{2}\) )
