Thermo Fluid

Question 1

Stirling engine 4 processed

Answer 1

1) isothermal compression
2) constant volume , pressure increase (heat addition )
3) isothermal expansion
4) constant volume pressure decrease ( heat rejection )

PV graph
-A to B curved up, B to C straight as constant volume , c to d curved down , d to A straight down as isothermal

Question 2

Answer 2

Steady flow
INVISCID means no viscous forces
No other mixing
