Question:-
Option (A)
    160 m3/s
Option (B)
    150 m3/s
Option (C)
    57.6 m3/s
Option (D)
    95.4 m3/s
Correct Option:
A
Question Solution:
    Area of catchment (km2) x 106 x =
    A = 345.6 km2
    Eqb. Discharge is because of cm/hr excess rainfall occurring over the catchment
    ∴ Q = 2.778 x = 160 m3/s
    
Question:-
Option (A)

Option (B)

Option (C)

Option (D)

Correct Option:
C
Question Solution:
    Work done on bar under suddenly applied load is = P.Δ Hence (c)
Question:-
Option (A)
    0.125 mm
Option (B)
    0.175 mm
Option (C)
    0.25 mm
Option (D)
    0.35 mm
Correct Option:
A
Question Solution:
    
    
    ΣMA = 0
    50 x 103 x 4 = (Kx + P)2
    ⇒ Kx + P = 105 ...(i)
    Compatibility : x =
    From (i) 105 =
    105 =
    P = 105 N
    ∴ x = = = 0.125 mm
Question:-
Option (A)
    1 - (1 - T)N
Option (B)
    
Option (C)
    
Option (D)
    
Correct Option:
B
Question Solution:
    Probability of occurring of flood =
    Probability of Non-occurrence of flood in N years =
    Probability of Non-occurrence of flood at least once is
Question:-
Option (A)
    0.55 m
Option (B)
    0.68 m
Option (C)
    0.60 m
Option (D)
    None of these
Correct Option:
D
Question Solution:
    Fr1 = = = 0.89
    as Fr1 < 1
    ∴ No jump formation hence (d)
