Question

Argon gas enters an adiabatic turbine steadily at 900 kPa and 450°C with a velocity of 80 m/s
and leaves at 150 kPa with a velocity of 150 m/s. The inlet area of the turbine is 60 cm2. If the
power output of the turbine is 250 kW, determine the exit temperature of the argon.
3- Helium is to be compressed from 120kPa and 310 K to 700kPa and 430K. A heat loss of
20kJ/kg occurs during the compression process. Neglecting kinetic energy changes, determine
the power input required for a mass flow rate of 90 kg/min.

Turbine.

Let's imagine that we have a fluid whose content of exploitable mechanical energy is high (flow energy, kinetic, potential, and thermal). The device that can convert this available energy into shaft power is the turbine.
