Consider an air$-$standard dual cycle. Operating data at principal states in the cycle are given in the table below. If the mass of air is $0\mathrm{.}05kg,$ determine

a$.$ the cutoff ratio.

b$.$ the heat addition to the cycle, in $kJ.$

c$.$ the heat rejection from the cycle, in $kJ.$

d$.$ the net work, in $kJ.$

e$.$ the thermal efficiency.
