What happen if the pressure get high inside the steam turbine condenser?
There has to be a built in expansion chamber or release valve. Otherwise the expansion would cause an explosion.
What causes steam turbine governor hunting?
inconsistent load will cause steam turbine hunting.
What are the effects of expansion and contraction?
Expansion and contraction can cause things to crack, as in the weathering of rock. They can cause a bi-metal strip to bend and straighten, which phenomenon is used in some thermostats. Expansion can cause the roadway of a bridge to buckle, so gaps have to be left. Obviously they cause the thread in a liquid-in-glass thermometer to get longer and shorter.
How do you control the control oil line vibrations in steam turbine?
If,clamp is not proper fitted in control oil line that time it may happen cause in control oil line pressure also more than main oil pump disch.
What is the difference between the Carnot cycle and the Rankine Cycle?
carnot cycle is a very ideal cycle that isn't practical at all , 'cause we add and reject heat isothermally , a wet mixture enters the turbine so it'll cause pitting and erosion and a wet mixture enters the pump , and the pump can't deal with a 2 phases fluid rankine cycle is a practical cycle but with a very low efficiency so the main difference lies in the adding and rejecting of heat

Why does heat cause expansion?
becuase of the increase in movement of molecules
Is the reverse current from the transformers can cause a damage to the turbine in power plant?
yes it will be big damages for both that's y fixing differential protection relay between both
How would an increase in total expenditures affects the national's economy?
An increase in total expenditures affect the nation's economy would cause an expansion.
Why would it be easy to crack a glass bottle when filled with water and subjected to a flame?
The temperature contrasts would cause differential expansion of the bottle which, being brittle, would cause the glass to crack.
What causes steam turbine governor hunting?
inconsistent load will cause steam turbine hunting.
How does the wind cause a turbine to spin?
turbines spin when there is a cause of wind..!!
What are the causes of power loss in generator- turbine system?
There are several causes that can cause a generator turbine system to lose power. The most common cause is a lack of fuel.
What are the causes of power loss in generator-turbine system?

What if Gina physician ordered laboratory test that would enable him to establish a differential to identify the cause of her signs and symptoms?
Differential Diagnosis
What is the increase in volume cause by a decrease in temperature?
It's called expansion, or thermal expansion. It's usually noted by the Greek character alpha.Most materials have alpha values greater than zero, so the thermal expansion occurs when temperature increases. However, some other materials have negative thermal expansion, as happens with water. Liquid water will increase its volume under cooling conditions below ~4 ºC. It will also increase it's volume as the temperature rises away from 4o C.
What are two factors that cause differential weathering?
stuff
