Given the operating conditions of the steam turbine shown, determine the isentropic efficiency. Question 1) \( 0.5 \mathrm{~kg} \) of ammonia in a piston is rapidly compressed from 4 bar at \( 30^{\circ} \mathrm{C} \), to 14 bar at \( 100^{\circ} \mathrm{C} \). The temperature of the air surrounding the piston is \( 20^{\circ} \mathrm{C} .72 \mathrm{~kJ} \) of work is used for this compression. Determine: a) The heat transfer of the system to the surrounds b) If the described process is possible. (Hint: make a judgment about the likely boundary temperature, consider testing extremes)
