4 A
company has two factories S1, S2 and two warehouses D1, D2. The supplies from S1
and S2 are 50 and 40 units respectively. Warehouse D1 requires a minimum of 20
units and a maximum of 40 units. Warehouse D2 requires a minimum of 20 units
and, over and above, it can take as much as can be supplied. A balanced
transportation problem is to be formulated for the above situation. The number
of supply points, the number of demand points, and the total supply (or total
demand) in the balanced transportation problem respectively are
A) 2, 4,
90
B) 2, 4, 110
C) 3, 4, 90
D) 3, 4, 110
Answer :
(C)
5 An incompressible fluid (kinematic viscosity, 7.4 x 10-7
m2/s, specific gravity, 0.88) is held between two parallel plates. If the top
plate is moved with a velocity of 0.5 m/s while the bottom one is held
stationary, the fluid attains a linear velocity profile in the gap of 0.5 mm
between these plates; the shear stress in Pascals on the surface of top plate
is
A) 0.651 x 10-3
B) 0.651
C) 6.51
D) 0.651 x 103
Answer
: (B)
