Is the pressure at the throat of a convergent-divergent nozzle highest or lowest?
coz area is less thats y pressure is more
How do you calculate the exit pressure of a nozzle?
How to calculate the ratio of the inlet-to-exit area of the nozzle
How do you use nozzle in a sentence?
My baby brothers baby bottle has a nozzle the size of an elephant!
What is the simplest engine that is made of burning chamber and nozzle?
the simplest engine that is made up of a burning chamber and a nozzle is a rocket.
What are the advantages and disadvantages of flow nozzle?
One disadvantage in the convergent-divergent nozzle as a shock wave can take place in the nozzle A nozzle is a device that converts pressure energy to kinetic energy (increasing fluid velocity on the account of static pressure) For a convergent nozzle there is no disadvantages as it can raise the fluid velocity only for the sonic speed the convergent-divergent type raises the velocity to over than sonic speed making supersonic flow, this could make a shock wave in the nozzle that turns the supersonic flow to subsonic flow
What is nozzleless propulsion?
Propulsion by means of uniform cross sectional ducts rather than a varying section (nozzle) is said to be nozzleless propulsion
What is the improtance of a rocket nozzle?
A rocket nozzle is crucial for the efficient conversion of high-pressure gas into thrust. It accelerates and directs the flow of exhaust gases out of the rocket engine to generate propulsion. The size and shape of the nozzle influence the velocity and efficiency of the exhaust gases, impacting the overall performance of the rocket.
What is the narrow opening at the tail end of a rocket?
The narrow opening at the tail end of a rocket is called the rocket nozzle. It is designed to control the flow and direction of the exhaust gases produced by the rocket engine, allowing for propulsion and steering of the rocket. The shape and size of the rocket nozzle are crucial in determining the performance of the rocket.
Do propulsion possible without nozzle?
YES!! propulsion is possible without nozzles contributing in weight reduction and cost reduction. It is only possible when the mass burning rate of fuel/propellant in the duct is increased to that extent to reach the sonic speeds. more likely to be used in missiles and rockets.
What is the difference between convergent divergent nozzle and venturi tube?
In case of venturi meter, at the diverging section mach number is less than 1. however in diverging section of a nozzle mach number is greater than 1.
What are the two purposes of the nozzle in a rocket engine?
To focus the controlled combustion blast of the ignited jet fuel, to achieve propulsion; and also to aim the force to alter trajectory (change direction).
What is the definition of turbo jet engine?
Turbojets consist of an air inlet, an air compressor, a combustion chamber, a gas turbine (that drives the air compressor) and a nozzle. The air is compressed into the chamber, heated and expanded by the fuel combustion and then allowed to expand out through the turbine into the nozzle where it is accelerated to high speed to provide propulsion.
Why do rockets have nozzles?
The nozzle directs the blast from the burning fuel into a propulsion cone that is the most efficient for the engines output. Without a cone the flow of energy would be unpredictable and would not propel the rocket in the direction desired.
How does a turbojet provide power to aircraft?
A turbojet consists of an air inlet, an air compressor, a combustion chamber, a gas turbine and a nozzle. Through this constructions, the turbojets provide power to an aircraft when the air is compressed into the chamber, heated and expanded by the fuel combustion and then allowed to expand out through the turbine into the nozzle where it is accelerated to high speed to provide propulsion.
WHAT IS SR Nozzle?
SR nozzle means "Self Reinforced Nozzle".
What are the three propulsion types?
The three main propulsion types are chemical propulsion, electric propulsion, and nuclear propulsion. Chemical propulsion uses chemical reactions to generate thrust, electric propulsion uses electric power to accelerate propellant to high speeds, and nuclear propulsion uses controlled nuclear reactions for propulsion.
How the space craft is propelled?
Spacecraft are propelled in different ways depending on their design and mission. Some spacecraft use chemical rockets for propulsion, where they expel propellant out of a nozzle to generate thrust. Other spacecraft use electric propulsion, such as ion thrusters, which accelerate ions to generate thrust. Solar sails can also propel spacecraft by harnessing pressure from sunlight.
