Production and Industrial Engineering Question set 1
Question:-
Option (A)
100 pF
Option (B)
50 pF
Option (C)
150 pF
Option (D)
125pF
Correct Option:
A
Question Solution:
Sensitivity=
=
50 x 10-12=
C=2 x 50 x 10-12 = 100 pF
Question:-
Option (A)
1
Option (B)
0
Option (C)
2
Option (D)
11
Correct Option:
A
Question Solution:
Since the eigen values of a real skew-symmetric matrix are purily imaginary or zero.
Letλ=bi(where i2 = -1)
= =
therefore, =
Question:-
Option (A)
- 1
Option (B)
0
Option (C)
Option (D)
1
Correct Option:
D
Question Solution:
If all the elements of a determinant located on one side of principle diagonal are 0, then
Δ=Product of the diagonal elements
therefore, Δ = 1
Question:-
Option (A)
Sensitivity will decrease
Option (B)
Sensitivity will increase
Option (C)
Pressure drop will decrease
Option (D)
Obstruction to flow will decrease
Correct Option:
B
Question Solution:
When the throat diometer is decreased, then the pressure at the thorat will be increase.
Therefore,(P2 - P1)=ΔP will increase
Sansitivity ∝ ΔP.
therefore, Sensitivity will be increased.
