Short Quiz 4 in Hydraulics (CE 326)

An open rectangular tank mounted on a truck is 5m long, 2m wide, and 2.5m high is filled with water to a depth of 2m. What maximum horizontal acceleration can be imposed on the tank without spilling any water and

• 1.962 m/s^2

• 1.692 m/s^2

• 2.291 m/s^2

• 2.691 m/s^2

A vessel containing oil is accelerated on a plane inclined 15° with the horizontal at 1.2 m/s2. Determine the inclination of the oil surface when the motion is upward.

A vessel 3m in diameter containing 2.4m of water is being raised. Find the pressure at the bottom of the vessel when it is accelerating 0.8 m/s^2 upwards.

• 22.454 kPa

• 25.464 kPa

• 23.544 kPa

• 24.564 kPa

In rectilinear translation, if an open rectangular container with the length (L) two times the height (H) moving horizontally is filled with 2/3H of water, will there be water spilled if the acceleration (a) is equal to acceleration due to gravity (g)?

• NO

• YES

In rotating vessel, considering an open cylindrical vessel with more than half filled of liquid, if y=H (y is the height of the paraboloid, H is the height of the vessel) the vortex touches the bottom of the container.

• TRUE

• FALSE

In rotating vessel, considering an open cylindrical vessel with more than half filled of liquid, if y/2 > D (y is the height of the paraboloid, D is the depth of the liquid from the top of the vessel) the vortex is within the container and there is NO spilled liquid.

• TRUE

• FALSE

In rotating vessel, considering an open cylindrical vessel with more than half filled of liquid, if y/2=D (y is the height of the paraboloid, D is the depth of the liquid from the top of the vessel) the vortex is within the container and there is NO spilled liquid.

• FALSE

• TRUE

In rotating vessel, considering a CLOSED cylindrical vessel with more than half filled of liquid, there will be NO liquid spillage.

• TRUE

• FALSE

In rotating vessel, considering an CLOSE cylindrical vessel with more than half filled of liquid, if y=H (y is the height of the paraboloid, H is the height of the vessel) the vortex lies at the bottom of the container.

• TRUE

• FALSE

In rotating vessel, considering a closed cylindrical vessel with more than half filled of liquid, if y > K (y is the height of the paraboloid, K = H^2/2D) there will be some liquid spilled.

• TRUE

• FALSE
