Given Information:
Inlet velocity = Vin = 25 m/s
Exit velocity = Vout = 250 m/s
Exit Temperature = Tout = 300K
Exit Pressure = Pout = 100 kPa
Required Information:
Inlet Temperature of argon = ?
Inlet Temperature of helium = ?
Inlet Temperature of nitrogen = ?
Answer:
Inlet Temperature of argon = 360K
Inlet Temperature of helium = 306K
Inlet Temperature of nitrogen = 330K
Explanation:
Recall that the energy equation is given by
Where Cp is the specific heat constant of the gas.
Re-arranging the equation for inlet temperature
For Argon Gas:
The specific heat constant of argon is given by (from ideal gas properties table)
So, the inlet temperature of argon is
For Helium Gas:
The specific heat constant of helium is given by (from ideal gas properties table)
So, the inlet temperature of helium is
For Nitrogen Gas:
The specific heat constant of nitrogen is given by (from ideal gas properties table)
So, the inlet temperature of nitrogen is
