Question

Calculate the enthalpy of steam p =20 and x=0.9

Answer 1

Enthalpy:

A thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume.

As we have

H=E+PV

V=120 for steam

=0.9+(20)(120)

$=2400.9 KJ \space answer$
