part II: Word problems
a.) Air is compressed slowly and frictionlessly in a cylinder according to the relationship pV^(1.4)=constant from an initial volume of 0.8 m³ and pressure of 100 kN/m² to a final volume of 0.4 m³. Calculate the work.
[ans: -63.9 kJ]
b.) Carbon dioxide is compressed frictionlessly in a steady-flow process in such a manner that Pv^(0.5) = constant from 100 to 500 kPa. The initial specific volume is 0.56 m^ 3 /kg. Calculate the work per kilogram of gas. Assume Delta pe = Delta ke = 0 .
[ans:-44.8 k]/kg]
proper solution please:
