The ability of a mass to do work by virtue of its velocity is called:

A body placed or immersed in a fluid is subjected to a buoyant force equal to the weight of the fluid displaced. This principle of buoyancy is attributed to:

Which of the following is considered a kinetic energy?

An opening with a closed perimeter through- which fluid flows whose purpose is to measure or control the flow is called:

Precise measurement of the specific weight of a liquid is done by using the principle of buoyancy and the device use for this is called:

What condition which will tend to produce laminar flow?

Hydrostatic forces acting on a plane surface is always acting perpendicular to the plane and is concentrated at the center of pressure. Where is the position of the center of pressure measured from the centroid of the plane surface?

The velocity of discharge from the orifice if there were no loss of head is called:

______ proved that the height of the column of mercury depended upon the atmospheric pressure when he carried a barometer to a higher elevation and found that the height of the column decreased as the altitude increased.

The actual velocity in the jet is less than the theoretical velocity because of the frictional resistance that occurs as the fluid enters and passes through the orifice. The ratio of the actual mean velocity to the theoretical velocity which would exist without friction is called:

_______ is defined as ability to do work

_______ is directly proportional to the kinetic energy of any mass having a certain velocity and is equal to the kinetic energy of 1 lb. of any mass moving with that velocity.

The inertia-surface tension ratio is referred to as:

The increase in kinetic energy is equal to the decrease in potential energy in a flow of water in a pipe is known as:

The main reason why the jet from the horizontal orifice would not rise as high as the liquid level in the supply tank because of the:

The pressure at which liquid will boil is called:

The flow is said to be ______ when its path lines are irregular curves, which continually cross each other and form a complicated network which in the aggregate represents the forward motion of the entire stream

The cross-sectional of the jet is similar to the shape of the orifice until the vena is reached. The cross-sections after the vena contracta is changed to different cross-sections of jets issued respectively from square, triangular, and elliptical orifices. This change in form, which is common to all shape of orifice is known as:

A gate which has its lower edge in or near the bed of a channel is called:

The particles of liquid approach the orifice in converging path from all directions. Because of the inertia of those particles with velocity components parallel to the plane of the orifice, they cannot make abrupt changes in their directions the instant they reach the orifice, and they therefore follow curvilinear paths, thus causing the jet to contract for a short distance beyond the orifice. This phenomenon is referred to as the contraction of jet. The section where the contraction caused by the orifice causes is called:

Molecules of liquid near the surface have greater attraction other than they do for molecules below the surface. Because of this membrane effect, each proportion of the liquid surface exerts tension on adjacent portions of the surface or objects that are in contact with the liquid surface. This tension acts in the plane of the surface and its magnitude per unit length is defined as:

Any particle of a stream of fluid has at any given instant a certain velocity, which is a vector quantity and therefore possesses both magnitude and direction. At the next instant forces acting on the particle may cause it to have a velocity which is different in the amount and direction. The path followed by a particle called _______ is ordinarily a curve in three dimensions.

Which of the following is considered a potential energy?

The inertia-elasticity force ratio is reffered as:

The hypothetical height of a column of air of unit weight that would produce standard atmospheric pressure.

The theoretical velocity of discharge from an orifice is the velocity acquired by a body falling freely in a vacuum through a height equal to the total head on the orifice is known as

The resultant buoyant force acting on the submerged body is equal to the weight of the displaced liquid, since in a homogenous fluid the center of gravity of the resultant buoyant force is called _______ which coincides with the center of the displaced fluid.

One way of expressing the equations for fluids in motion which considers individual fluid particle for all time. The particle velocity is obtained by differentiating the particles position vector with respect to time. This is called:

A converging tube attached to the end of a pipe or hose which serves to increase the velocity of the issuing jet is called:

Study of liquids that are in motion with respect both to the earth and their containers is called:
