AI Thread Summary
To determine the power required to run a turbine, it's essential to calculate the torque needed to achieve the desired rotational speed. The steam pressure necessary to maintain this power output is influenced by several factors, including the size and length of the steam pipes, the temperature of the steam, and steam losses at the interface between the pipe and turbine. A straightforward application of formulas will not suffice due to these complexities. Understanding these variables is crucial for accurate power and pressure calculations. Proper assessment of these factors will lead to more effective turbine operation.

I want to find out the power required to run the turbine and the pressure of steam required to maintain the power requirement of turbine. Please tell me about any formula or method to resolve this issue.

I think a good place to start would be to determine the torque required to turn the turbine at the speed you require, i.e the turning force.

Unfortunately it's not going to be as simple as applying a few equations. The pressure of steam required will depend on the pipe size feeding to the turbine, its length, temperature and also how much steam is lost at the pipe-turbine interface.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
