The work done by the turbine will be 708.2 kJ/kg. The work done by the turbine is the difference of the enthalpy at inlet and exit.
<h3 /><h3>What is temperature?</h3>Temperature directs the hotness or coldness of a body. In clear terms, it is the method of finding the kinetic energy of particles within an entity. Faster the motion of particles, more the temperature.
If the given turbine is assumed to be reversible;
(Initial pressure)=60 mpa = 60 bar
(Initial temperature)=600° C
(Exit pressure)=600 kpa=6 bar
The heat balance equation is;
The change in the entropy is;
The work done by the turbine is;
Hence,the work done by the turbine will be 708.2 kJ/kg.

Answer:
The current is halved
Explanation:
The relationship between the current and the resistance is given by Ohm's Law, as follows:
where,
V = Voltage
I = Current
R = Resistance
Therefore, if we double the resistance:
Hence the correct option is:
<u>The current is halved</u>
Answer:
Explanation:
Given
In R-L-C circuit frequency is very high
Inductive Reactance for inductor is given by
Inductive Reactance for Capacitor is given by
as frequency becomes too high then will become very large and and
will be approximately zero .
In other words inductor behave as a very high resistance and Capacitor behaves as very small resistance
