Which solid does not have a uniform cross section?

Which solid does not have a uniform cross section?

Prisms and cylinders have uniform cross-sections, but pyramids and cones do not.

What is flowing in a horizontal pipe of non uniform cross section at the most contracted place of the pipe?

Water
Water is flowing through a horizontal pipe of the non-uniform cross-section.

What is uniform cross sectional area?

Lesson Summary. Uniform means identical, or exactly the same, and a cross section is when you cut an object in half and reveal the shape inside. So a uniform cross section is when you cut an object straight through, and the resulting shape inside matches the bases, or ends, of the shape exactly.

How do you know if a solid has a uniform cross section?

Solids and cross-sections. A solid has uniform cross-sections if, in some direction, every cross sectional area has the same shape: i.e. every cross-section is always a square, a rectangle, an equilateral triangle, a circle, etc.

What is a uniform cross-section of a prism?

A prism is a solid with a uniform cross-section . This means that no matter where it is sliced along its length, the cross section is the same size and shape (congruent).

What shape is a 3D cross?

prism
A prism is a 3D shape which has a constant cross section – both ends of the solid are the same shape and anywhere you cut parallel to these ends will give you the same shape. For example, in the prism below, the cross section is a hexagon.

When a fluid passes through the narrow part of a horizontal pipe of non uniform cross sectional area which one of the following statements is correct?

Correct option (a) The velocity is maximum at the narrowest part of the pipe and pressure is maximum at the widest part of the PiPe. Hence, when a fluid flow across a horizontal pipe of variable area of cross-section its velocity is maximum and pressure is minimum at the narrowest part and vice versa.

What is the length of a cross section?

The cross section of a solid is a plane section resulting from a cut (real or imaginary) perpendicular to the length (or breadth of height) of the solid. If the shape and size of the cross section is the same at every point along the length (or breadth or height) of the solid then the cross section is uniform.

How do you find cross sectional area?

The volume of any rectangular solid, including a cube, is the area of its base (length times width) multiplied by its height: V = l × w × h. Therefore, if a cross section is parallel to the top or bottom of the solid, the area of the cross-section is l × w.

What is a 3 dimensional square called?

A three-dimensional orthotope is also called a right rectangular prism, rectangular cuboid, or rectangular parallelepiped.

What is a cross-section of a shape?

In geometry and science, a cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces. Cutting an object into slices creates many parallel cross-sections.

When does a non uniform cross-section allow water to flow?

A horizontal pipe of non – uniform cross – section allows water to flow through it with a velocity 1ms ^-1 when pressure is 50kPa at a point. If the velocity of flow has to be 2 ms ^-1 at some other piont,the pressure at that point should be: 11th

What is the flow velocity of a non uniform cross section pipe?

A horizontal pipe of non uniform cross section has water flow through it such that the velocity is 2ms−1 at a point where the pressure is 40kP a. The pressure at a point where the velocity of water flow is 3ms−1 is : ( in kP a)

When does a horizontal pipe allow water to flow?

> A horizontal pipe of non – A horizontal pipe of non-uniform cross-section allows water to flow through it with a velocity 1ms −1 when pressure is 50kPa at a point. If the velocity of flow has to be 2 ms −1 at some other piont,the pressure at that point should be:
