There is a 1 mm thick layer of oil between a flat plate of area 10-2 m2 and a big plate. How much
force is required to move the plate with a velocity of 1.5 cm/s2? The coefficient of viscosity of oil
is 1 poise-
(A) 1.5 X 10- N (B) 1.3 x 10-5 N C 15 Y 10-2 M ini

Answer 1

Answer:

F = n A dv/dy

n = coefficient of viscosity

F = 1.5 × 10^-2

A = 10^-2

dv = 1.5 × 10^-2

dy = 1mm = 10^-3
