Negative expansion in a turbine occurs when the turbine suffers from a loss of power output due to factors like fouling or damage. Positive expansion, on the other hand, would refer to the ideal scenario where a turbine operates efficiently and produces the expected power output.

What are the key principles of positive and negative energy science and how do they impact our understanding of the universe?
Positive and negative energy are key principles in science that impact our understanding of the universe. Positive energy is associated with growth, expansion, and creation, while negative energy is linked to contraction, destruction, and decay. These concepts help explain the balance and dynamics of energy in the universe, influencing everything from the behavior of particles at the quantum level to the expansion of the cosmos on a cosmic scale. By studying the interplay of positive and negative energy, scientists gain insights into the fundamental forces and processes that shape the universe.
What are the negative and positive parts of an atom?
Negative: The negative part of an atom is the electrons which have a negative charge and orbit around the nucleus. Positive: The positive part of an atom is the nucleus which contains protons with a positive charge.
What is difference between positive and negative conductor?
There is no positive and negative conductor. There are just two ends of a conductor, namely positive and negative. It is usually said that electricity flows from the positive to the negative side of a conductor, but scientists have discovered, that current consists of electrons that always flows from the negative to the positive side.
Is the keyword "positive" into the page positive or negative?
The keyword "positive" on a webpage can have either a positive or negative connotation, depending on how it is used in the context of the content.
Is the keyword "k" negative or positive?
The keyword "k" is neutral and does not have a positive or negative connotation.
Turbine differential expansion should be positive or negative?
Turbine diff expansion can be positive or negative and depends on the convention used. The usual convention is that positive expansion is rotor expanding faster (hotter) than fixed components. Expansion is dictated by steam flow, gland steam temperatures etc
Why LP turbine diaphragm breaks?
Lp turbine diaphragm breaks due to positive pressure inside the condenser because of steam expansion.
What were the positive and negative results of the Jacksonian democracy?
The positive results were the expansion to the west and the negative effects was the Indian removal act
What is expansion turbine?
differential expansion is refer to differential distance between rotor blade and fix blade.rotor expand toward generator and casing expand toward control valve.when temperature increase ,expansion in casing and rotor.so rotor mass is less than casing which rotor expand more than casing.
What is HP and LP turbine expansion?
HP Turbine is High Performance Turbine LP Turbine is Low Performance Turbine
What is positive differential expansion of steam turbine?
Differential expansion means gap between fixed Blade & rotating blase of a turbine.. When steam enters into the turbine, rotor tends to expand towards generator side & casing tends to expand towards control valve side. If differential expansion increase then there is a possibility of reducing axial gap between rotor & fixed blades. When differential expansion is positive its means rotor expand more than the casing expansion. There is a limit upto +ve 5. If increases than +ve 5 it means we have to check front side tie rods status.
What to do about turbine rotor differential expansion?
my LP turbine differential expansion increase ,when rated gland steam temperature maintain.
What is absolute expansion of steam turbine?
it's the thermal expansion in the casing of hp or ip turbine can be noticed by journal or thrust bearing when moving <<
Is a positive plus a negative make a positive or a negative?
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
What is a negative - positive?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
How is dividing integers similar to multiplying integers with the resulting sign?
The rules for the sign (positive or negative) of the result of a multiplication is the same as division. For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
If a negative is divided by a positive is it negative?
Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative
