Product of pressure or specific volume not a volume.

Basically enthalpy is total amount of heat present in the system. It is an intensive property.

Thank you all for explaining.

Here, H = U + p * V.

Deepak said:   9 years ago
In actually, what is enthalpy? With examples.

Milad H. Mekari said:   9 years ago
Also dq = du + pdv = element heat/energy added to the thermodynamic system, that include both the Enthalpy & Entropy.

H = U+PV.

Where, H = Enthalpy,
U = Internal energy,
PV = Product of pressure & volume.

MATHEMATICAL EQUATION:

H = U+PV

Anand sharaf said:   1 decade ago
Internal energy(U) + Flow work(p*v) = Enthalpy(H).
