In point (b):
formula:
that's why the composition value equal to 99.63 %
Answer: = 28800 Pa or 28.8 kPa
Explanation: To determine the pressure of a liquid in a rotating tank,it is used:
p = - γfluid . z + c
where:
is the liquid's density
w is the angular velocity
r is the radius
γfluid.z is the pressure variation due to centrifugal force.
For this question, the difference between a point on the circumference and a point on the axis will be:
=
- γfluid.
- (
- γfluid.
)
=
- γfluid(
-
)
Since there is no variation in the z-axis, z = 0 and that the density of oil is 0.9.10³kg/m³:
=
= 28800
The difference in pressure between two points, one on the circumference and the other on the axis is = 28800 Pa or 28.8 kPa
