Air enters a turbine operating at steady state at 8 bar, 1400 k and expands to 0.8 bar. the turbine is well insulated, and kinetic and potential energy effects can be neglected. assuming ideal gas behavior for the air, what is the maximum theoretical work that could be developed by the turbine in kj per kg of air flow?

Biased means unfair but that's all ik

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.

'b ' is the correct conclusion.
