Answer to Question #189844 in Molecular Physics | Thermodynamics for Aryan

Question

Steam at 30 bar is contained in a cylinder behind a piston the initial volume being 0.08067 m'kg calculate the heat flow to or form cylinder and the work done by the steam a) According to the low pys - C to final volume 0.2 m / kg. b) According to a linear law to final dry saturated volume of 0.1047m / kg

Answer 1

$A=p\Delta V,$

a)

$A_1=p(V_2-V_1)=358~kJ,$

b)

$A_2=p(V_3-V_1)=72~kJ.$
