3) Find the complement of the following expression. Then, simplify the complement as much as you can. (Only single variables may be complemented in your answer --- (a+b)’ is not acceptable part of answer format). (a + b)(b’ + c) + d’(a’b + c)

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
