    Thermodynamics: Pressure and temperature from turbine

    P2 and T2 are the temperature and pressure at the exit of the turbine, and in this problem they are both unknowns. I do however know what their values are supposed to be: P2 = 293KPa, T2 = 1063K I just do not know how to get there with what I have.

    Thermodynamics: Pressure and temperature from turbine

    Homework Statement A turbine is receiving air from a combuster inside of an aircraft engine. At the inlet of the turbine I know that T1 = 1273 K and P1 = 549 KPa, and the velocity of the air is essentially 0. The turbine is assumed to be ideal, so its efficiency is exactly 1. Also: R = 287...

    What are the forces acting on point A in this statics problem?

    1) According to Newton's 3rd Law, for every action there is an equal and opposite reaction. Meaning, if you pull or push on something, it will pull or push back. The cable in this problem pulls on point B just as much as it pulls on point A, but they only ask you to consider point A. 2) If...
