Hydraulics Lab Reviewer-quiz For Finals

In most cases, weirs take the form of a ______, smaller than most conventional dams,

They are commonly used to alter the flow regime of the river, prevent flooding, measure discharge and help render a river navigable.

Give one of the notches used in Exp. 1.

In one of the Exp.1 procedures:Mount the rectangular notch plate into the flow channel and position the stilling _______.

In one of the Exp.1 procedures:Adjust the valve to give approximately ___ mm depth above the notch base. 

In one of the Exp.1 procedures:To take an accurate height reading, use the ______________ to lower the gauge until the point touches its reflection in the surface (to achieve this, you will need to have your eye level just above the surface). 

In one of the Exp.1 procedures:Volume flow rate is done by using the ______ valve to close the tank outflow and then determine the volume collected from the sight-glass.

After using the rectangular notch in Exp.1, it is replaced by a vee notch plate and repeat the procedures. In the vee notch, you will need to work with height increments of _ to _ mm.

What is the width (meters) of the rectangular notch in Exp. 1?

What is the angle of vee notch in Exp. 1?

This discharge coefficient formula is used in what notch?

The procedure in Exp.1 is repeated having opened the bench valve further, to produce an increase in depth of approximately 10 mm.

As water flow is being increased in Exp.1, spillage should occur over the plate top adjacent to the notch.

This discharge coefficient formula is used in what notch?

What is the title of Exp. 1?

In pipes, friction will occur between the layers within the fluid. This movement of fluid elements relative to each other is associated with pressure drop, called _________ losses.

Give an example of a pipe material with smooth walls.

Give an example of a pipe material with LESS smooth walls.

The velocity profile in a pipe will show that the fluid elements in the center of the pipe will move at a higher speed than those closer to the wall.

The diameters of pipe used in Exp. 2 are __mm and then __mm.

The manometer used in Exp. 2.

The objective of Exp. 2 is to measure the loss of head and the _______ factor in pipes.

In one of the procedures in Exp. 2:Regulate the flow by using ________ valve and the outlet valve to procedure the minimum pressure differential between the ends of pipe.

What is the title of Exp. 2?

The objective of Exp. 3 is to determine the loss factors for flow through a range of pipe fittings including bends, a __________, and enlargement.
