Chromosomes that's the answer
In my school, a student
who refuses to wear their uniform gets suspended.
<span>Our school is quite strict
when it comes to our uniform. If you get caught with your tie off, an undone
button or untucked shirt, you will get a 45-minute detention after school.
Sometimes, when a student doesn’t wear their school uniform and the security
guard or the discipline officer catches them, they may also be required to do
community service or have their ID confiscated. Most of the time, this is done
so a student would be a better person that follows the protocols set by an
institution, and this makes a student prepared for the real world, equipped
with good values.</span>
Answer:
638.8kW
Explanation:
The flow rate of the steam m = 22kg/s
The Pressure of the steam at the inlet of the turbine P1 = 1.6MPa
The temperature of the steam at the inlet of the turbine T1 = 350*C
Steam quality at the exit of the turbine x2 = 1.0
The temperature of the steam at the exit of the turbine T2 = 30*C
Power produced = 12,350kW
Assuming the turbine is running on a steady state, hence we neglect the effect of kinetic and potential energy we get:
If you refer to the superheated steam table for the specific enthalpy at a pressure of 1.6MPa and temperature of 350*C, we get
h1 = 3,146kJ/kg
Refer to the steam table for saturated gas at temperature 30*C to get the specific enthalpy value h2 = 2,556.81kJ/kg
The heat that comes out from the turbine can be defined from the balance of energy in the system, and is represented as
Ein - Eout = change in system Energy = 0
Thus Ein = Eout
mh1 = mh2 + Wout + Qout
Qout = m(hi-h2) - Wout
Qout = 22 x (3146-255.6) - 12350
Qout = 638.8kW
