Answer:
2074.2 KW
Explanation:
<u>Determine power developed at steady state </u>
First step : Determine mass flow rate ( m )
m / Mmax = ( AV )₁ P₁ / RT₁ -------------------- ( 1 )
<em> where : ( AV )₁ = 8.2 kg/s, P₁ = 0.35 * 10^6 N/m^2, R = 8.314 N.M / kmol , </em>
<em> T₁ = 720 K . </em>
insert values into equation 1
m = 0.1871 kmol/s ( mix )
Next : calculate power developed at steady state ( using ideal gas tables to get the h values of the gases )
W( power developed at steady state )
W = m [ Yco2 ( h1 - h2 )co2

Explanation:
Thermodynamics system :
Thermodynamics system is a region or space in which study of matters can be done.The system is separated from surroundings by a boundary this boundary maybe flexible or fixed it depends on situations.The out side the system is called surroundings.
Generally thermodynamics systems are of three types
1.Closed system(control mass system)
Only energy transfer take place ,no mass transfer take place.
2.Open system(control volume system)
Both mass as well as energy transfer take place.
3.Isolated system
Neither mass or nor energy transfer take place.
At steady state ,property is did not changes with respect to time.

Hello!
To solve this exercise follow the steps below.
1. Find the power the generator needs to operate at 100Kw,
This is done by remembering that efficiency in a generator is the ratio between real power and ideal power.
where
α=generator efficiency =0.9
Wi=nominial or ideal efficiency=100Kw
Wr=real effiency
solving for Wr
the power that the combustion engine must deliver is 111Kw for the generator to deliver 100Kw, Now use conversion factor to know the value in horsepower
2. Find the engine supply power using the combustion engine efficiency definition
α=engine efficiency =0.35
Wo = output power
=111.11Kw
Wi = supply power
solving for Wi
3. use the calorific power of diessel (CP=45KJ /g) to find the mass flow, remember that the supply power is the product of the mass flow and the caloric power
Wi=m(CP)
m=mass flow
solving for m
4. The mass flow is the ratio between the mass consumed and the time (1h) in this way we can find the diessel consumed in one hour at full load
M=diessel mass consumed
m=M/t
M=mt
