What is nozzle in physics?
A nozzle is a relatively simple device, just a specially shaped tube through which hot gases flow. Rockets typically use a fixed convergent section followed by a fixed divergent section for the design of the nozzle. This nozzle configuration is called a convergent-divergent, or CD, nozzle.
What is nozzle in turbine?
All gas turbine engines have a nozzle to produce thrust, to conduct the exhaust gases back to the free stream, and to set the mass flow rate through the engine. The nozzle sits downstream of the power turbine. A nozzle is a relatively simple device, just a specially shaped tube through which hot gases flow.
What is nozzle in thermodynamics?
A nozzle is a device that increases the velocity of a fluid at the expense of pressure. A diffuser is a device that increases the pressure of a fluid by slowing it down. The cross sectional area of a nozzle decreases in the flow direction for subsonic flows and increase for supersonic flows. Fig.
What is nozzle Mcq?
This set of Steam and Gas Turbines Multiple Choice Questions & Answers (MCQs) focuses on “Design of Nozzles”. 1. Nozzle is used to control direction or characteristics of flow. Explanation: Nozzle is used to control the direction and characteristics of flow.
What is the principle of nozzle?
When a flow nozzle is placed in a pipe carrying whose rate of flow is to be measured, the flow nozzle causes a pressure drop which varies with the flow rate. This pressure drop is measured using a differential pressure sensor and when calibrated this pressure becomes a measure of flow rate.
What are the different types of nozzle write its applications?
There are following applications of a nozzle are:
- Nozzles are used in steam turbines, gas turbines, water turbines and in jet engines, Jet propulsion.
- Nozzles are used for flow measurement e.g. in venturimeter.
- Nozzles are used to remove air from a condenser.
- Injectors for pumping feed water to boilers.

What is use of nozzle?
A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them.
What is nozzle used for?
How is a nozzle?
What are the different types of triangles in math?
A triangle’s type depends on the length of its sides and the size of its angles (corners). There are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene. The green lines mark the sides of equal (the same) length.
What is a nozzle?
A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe . A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid ( liquid or gas ).
What are the characteristics of a triangle?
The triangle is one of the strongest shapes and hence it is used in construction for its rigidity and stable shape. 1. 2. 3. 4. 5. The characteristics of a triangle’s sides and angles are used to classify them. The different types of triangles are as follows: On the basis of side lengths, the triangles are classified into the following types:
Which triangle has no equal sides?
The triangle with no equal sides is the scalene triangle. Each line of this triangle is of different length. Following is the figure of the scalene triangle: This triangle consists of one right angle and two acute angles. The right angle is an angle that measures 90° and the acute angles are those angles that measure less than 90°.
