Sample questions

1. 1.A spray pump tube of cross-section 8.0 cm^2 has 40 fine holes each of diameter 1.0 mm. If the liquid flow inside the tube is 1.5 m/min, the speed of ejection of liquid through the holes is approximately:
   • A.0.64 m/s
   • B.1.5 m/s
   • C.0.025 m/s
   • D.9.6 m/s
2. 2.The dimensions of pressure are:
   • A.[ML^-1 T^-2]
   • B.[ML T^-2]
   • C.[ML^-3]
   • D.[ML^-1 T^-1]
3. 3.The path taken by a fluid particle under steady flow, whose tangent at any point gives the direction of fluid velocity, is called a:
   • A.streamline
   • B.turbulent eddy
   • C.isobar
   • D.node
4. 4.Assertion (A): Bernoulli's equation cannot be applied accurately to the flow of water through a rapid in a river. Reason (R): Flow through a rapid is turbulent and not steady, and Bernoulli's equation holds only for steady, non-viscous, incompressible flow.
   • A.Both A and R are true and R is the correct explanation of A
   • B.Both A and R are true but R is NOT the correct explanation of A
   • C.A is true but R is false
   • D.A is false but R is true
5. 5.A thin soap film formed in a U-shaped wire frame supports a light slider of length 30 cm together with a weight, totalling 1.5 x 10^-2 N. What is the surface tension of the film? (Recall a soap film has two surfaces.)
   • A.0.05 N m-1
   • B.0.025 N m-1
   • C.0.5 N m-1
   • D.0.0125 N m-1
