Answer:
3.983 MW
Step-by-step explanation:
Given that:
At the inlet:
Velocity (v₁) = 30 m/s
Enthalpy (h₁) = 3348 kJ/kg
At the outlet:
Velocity (v₂) = 60 m/s
Enthalpy (h₂) = 2550 kJ/kg
Mass flow rate (m) = m₁ = m₂ = 5kg/s
According to the steady flow energy equation:
Since the elevation (z) is negligible and flow via the turbine is adiabatic:
Then,
Q = 0 and z₁ = z₂
∴
