Ammonia steadily flows at 2.64 lbm/s into an adiabatic compressor as a saturated vapor at 30 F and negligible velocity. The shaft power delivered to the compressor is 106 Btu/s. The fluid exits at 90 psia and 1004 fps [feet per second]. It then flows through an adiabatic diffuser and exits at 130 psia, 140 F, and 10 fps. Neglect potential energy effects. a) Determine the compressor's exit specific volume [ft³/lbm], and b) the diffuser's area ratio (Aexit/Ainlet). c) Draw T-v state diagrams showing the states and processes

![**Problem Statement:**
Ammonia steadily flows at 2.64 lbm/s into an adiabatic compressor as a saturated vapor at 30°F with negligible velocity. The shaft power delivered to the compressor is 106 Btu/s. The fluid exits at 90 psia and 1004 fps [feet per second]. It then flows through an adiabatic diffuser and exits at 130 psia, 140°F, and 10 fps. Neglect potential energy effects.
**Tasks:**
a) Determine the compressor’s exit specific volume [ft³/lbm].
b) Determine the diffuser’s area ratio \((A_{\text{exit}}/A_{\text{inlet}})\).
c) Draw T-v state diagrams showing the states and processes.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F058a51dd-affc-487e-bd55-c7137d1b5904%2Fa8a7d33e-acd8-454c-b3b3-2cbd70fbe019%2Fz9xbvkr_processed.jpeg&w=3840&q=75)
