An adiabatic turbine operates at steady state. Air enters the turbine at a pressure and temperature of 800kPa and 1100K, respectively, and exits at 100kPa. A temperature sensor at the turbine exit indicates that the exit air temperature is 700K. Kinetic and potential energy effects are negligible, and the air can be treated as as ideal gas. Determine if the exit temperature reading can be correct. If yes, determine the turbine isentropic efficiency.
Correct?
If the speed of the man at A (XA = 5m and YA = 1m) is VA = 9 m/s and the increase of his speed is dVA/dt = 13 m/s2, calculate the magnitude of his acceleration and the slop angle at this point.
Air enters a one-inlet, one-exit control volume at 6 bar, the pressure is 3 bar, the temperature is 456.5 K, and the velocity is 300 m/s. The air behaves as an ideal gas for steady-state operation, determine: (a) the mass flow rate in kg/s (b) the ex..
A steam power plant operates on a simple Rankine Cycle between the pressure limits of 10MPa and 50kPa. The mass flow rate of the steam is 50kg/s. The quality of the steam at the turbine exit is 90%.
