An uninsulated, irreversible steam engine whose surface temperature is 200.°F produces 50.0 hp with a steam mass flow rate of 15.0 lbm/min. The inlet steam is at 400.0°F, 100. psia and it exits at 14.7 psia, 90.0% quality. Determine
a. The rate of heat loss from the engine.
b. Its entropy production rate.
c. Its entrance and exit specific flow availabilities. Use saturated liquid water at 80.0°F as the local environment (ground state).
