Given that, .
The initial gas pressure is
P1 = 3 MPa
The initial gas temperature
T1 = 300°C
The final gas pressure is
P2 = 80 KPa
Which are of two choices
1. Air with an isentropic expansion of 90% efficiency
2. Neon with an isentropic expansion of 80% efficiency
We want to know which will produce more work
Answer:
i hope this will help you :)
Explanation:
mass=19kg
density=800kg/m³
volume=?
as we know that
density=mass/volume
density×volume=mass
volume=mass/density
putting the values
volume=19kg/800kg/m³
so volume=0.02375≈0.02m³
