A closed, 0.4-m-diameter cylindrical tank is completely filled with oil (SG 0.9)and rotates about its vertical longitudinal axis with an angular velocity of 40 rad/s. Determine the difference in pressure just under the vessel cover between a point on the circumference and a point on the axis

= 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
