1. 1996 Q24 P1
State how the pressure in a moving fluid varies with the speed of the fluid (1 mark)
2. 1997 Q18 P1
Water flows in a horizontal smooth pipe. State the changes that would be observed in the nature of the flow if the speed of the water is steadily increased from low to a high value
3. 1998 Q30 P1
Fig 9 shows a Bunsen burner.
4. 1999 Q25 P1
Figure 13 shows a section of a pipe PQ. A constant pressure difference maintains a streamline flow of a liquid in the pipe.
5. 2000 Q25 P1
A student holds a sheet of paper at one end so that it hangs in the position A shown in fig. 14
6. 2001 Q23 P1
Fig. 16 shows a non – viscous fluid flowing through a pipe a long which vertical tubes A, B and C have been fitted.
Complete the diagram by indicating the possible levels of the fluid in tubes B and C.
8. 2003 Q36 P1
Figure 19 shows a pith ball placed in a flask. When a jet of air is blown over the mouth of the flask as shown, the pith ball is observed to rise form the bottom
9. 2005 Q26 P1
State Bernoulli’s principle. (1 mark)
10. 2006 Q11 P1
A pipe of radius 6 mm is connected to another pipe of radius 9 mm. If water flows in the wider pipe at the speed of 2 ms-1, what is the speed in the narrower pipe? (3 marks)
11. 2007 Q3 P1
Figure 2 shows a tube of varying cross sectional area
12. 2008 Q12 P1
Fig. 6 shows a sheet of paper rolled into a tube.
13. 2009 Q11 P1
Figure 6 shows two inflated ballons hanging vertically on light threads
14. 2010 Q7 P1
Figure 4 shows a horizontal tube with two vertical tubes x and y. water flows through the horizontal tube from right to left. The water level in tube x is higher than water in tube y.
15. 2012 Q14 P1
1. An aeroplane is moving horizontally through still air at a uniform speed. It isobserved that when the speed of the plane is increased, its height above the ground increases. State the reason for this observation. (1 mark)
(b) Figure 5 shows parts A, B and C of a glass tube.
