What is meridional plane in a centrifugal compressor?
If we consider the longitudinal cross section of the single stage of CFC disc, then the plane containing the impeller blade section with hub & shroud is known as the Meridional Plane.
What is the cooling system of gas turbine blade?
In order to enhance creep life of gas turbine blade, it is required to keep blade at lower temperature, hence internal cooling of blade is done.
What are the main reason of turbine blade failure?
What are the main reason of turbine blade failure?
What is the centrifugal force on a turbine blade if a London bus is hanging from the blade?
A ball park figure for the weight of a double decker bus might be about 15,000 kilograms. But to calculate the centrifugal force on a turbine blade with this hanging from it would require the blade length and the rotational speed of the turbine.
What are the other terms of propeller blade?
may i know the other term of propeller blade particular in ship propeller There is no alternative term for "propeller blade", but the entire prop is sometimes called a screw.
What is turbine blade angel?
turbine blade angle is that angle with which,a high presseure & high temprature steam is made to empenge on it.
What is variable pitch?
A controllable-pitch propeller is a blade whose blade angle may be adjusted to any angle between the low and the high pitch limits.
What is blade pitch of a helicopter?
The angle of the rotor blades.
The angle formed between the blade and the shaft of a hockey stick is 135 What type of angle is this?
Obtuse.
What is an angledozer?
An angledozer is a bulldozer whose blade can be tilted at an angle.
What is a pat blade?
PAT stands for Power, Angle, Tilt.
what is angledozer?
An angledozer is a bulldozer whose blade can be tilted at an angle.
What is difference betweenrotar of centrifugal pump and compressor?
pump is used to handle liquid and compressor is used to handle gases. other difference include blade shape etc..
What increases the thrust of an helicopter?
The 'angle of incidence ' of the rotor blades and blade speed.
Why do helicopters make noise?
The source of the noise made by Helicopters are created by several things. The engines can make noise just like any airplane. The transmissions can make a high frequency noise. The destinctive sound of helicopters is the "whop-whop-whop" it makes. This is caused by the rotor blades as it rotates.One reason for this sound is one blade passes and creates a vortex(or whirling tunnel of air) and then the next blade slaps this vortex.Another reason is that each blade must change pitch angle as it rotates around the central mast. When the blade is on one side of the helicopter, it has a high pitch and creates a high lift and therefore a large turbulent vortex. Then as it rotates to the other side of the helicopter, the blade must decrease its pitch angle, sometimes to almost zero angle. This rapid change in high blade angle and low angle causes this blade sounds.newtest3
Is a knife blade a conductor or a insulator?
Conduction or insulation depends on material, not shape or purpose. A metal blade is a conductor.
What is the best angle for an air propeller?
The best "angle of attack" for a propeller depends on many factors, the main ones being: the speed of airflow over the blade; the distance along the blade from the centre of revolution; the physical dimensions of the blade; the density of the air which it is trying to pull, or to push, to produce the force called "thrust" which drives the blade, and the aircraft attached to it, through the air. That is why the blade does not have a simple flat surface, but one which has many angles of attack along the blade due to the complicated shape of the blade.
