Steam at 150 bars and 600°C passes through process equipment and emerges at 100 bars and 700°C. There is no flow of work into or out of the equipment, but heat is transferred.

(a) Using the steam tables, compute the flow of heat into the process equipment per kg of steam.

(b) Compute the value of enthalpy at the inlet conditions, Hⁱⁿ, relative to an ideal gas at the same temperature, H^ig. Consider steam at 1 bar and 600°C as an ideal gas. Express your answer as (Hⁱⁿ – H^ig)/RTⁱⁿ.
