SECTION A (75 Marks)CE-l. This question consists of TWENTY FIVE sub-questions (1.1 - 1.25) of ONE mark each. For each of these sub-questions four possible answers (A, B, C and D) are given, out of which ONLY ONE is correct. Answer each sub question by darkening the appropriate bubble on the OBJECTIVE RESPONSE SHEET (ORS) using a soft HB pencil. Do not use the ORS for any rough work. . You may use the Answer Book for any rough work, if needed.

1.14 The observed value of the standard penetration number (N) at 10m depth of a silty
sand deposit is 13. The unit weight of the soil is 16 kN/in 3.The N value after correcting for the presence of fines will be:
1.15 The force 'F' required at equilibrium on the semi-cylindrical gate shown below is:
1.16 Velocity distribution in a boundary layer flow over a plate is given by
(u/u m) = 1.5 h - 0.5 h 3 J
where, h = y/ d ; y is the distance measured normal to the plate; d is the boundary layer thickness; and U m is the maximum velocity at y = d . If the shear stress t , acting on the plate is given by
t =K( m u m)/ d
where, m is the dynamic viscosity of the fluid, K takes the value of:
(0) none of the above
