Answer:
(a) Relative Humidity = 48%,
Specific humidity = 0.0095
(b) Enthalpy = 65 KJ/Kg of dry sir
Specific volume = 0.86 m^3/Kg of dry air
(c/d) 12.78 degree C
(e) Specific volume = 0.86 m^3/Kg of dry air
Answer: Gasoline cars are bad because
Explanation: They give off carbon emissions and pollute the ozone layer causing the greenhouse effect which leads to global warming
Answer:
Explanation:
Given
From Clausius inequality
=Reversible cycle
=Irreversible cycle
=Impossible
(a)For
Rejected heat
thus it is Impossible cycle
(b)
Possible
(c)Carnot cycle
and maximum Work is obtained for reversible cycle when operate between same temperature limits
Thus it is possible
Answer:
The thermal efficiency of cycle is 42.6%.
Explanation:
Given that
mass flow rate = 6 kg/s
Compression ratio = 7
Turbine inlet temperature = 1200 K
γ=1.4
We know that thermal efficiency of Brayton cycle given as
Now by putting the values
η=0.426
So the thermal efficiency of cycle is 42.6%.
