Physics Help Forum Actual Total enthalpy Basic Problem

Determine the Actual total enthalpy and Actual specific volume. Given: Actual total enthalpy = hf + hfgX Actual specific volume = VgX No problem right? Thing is, the lecturer had actually given the same calculation in notes he handed out months ago, its in the reply to this message. For Actual total enthalpy i got: 670.56 + (2086.3*0.94) = 2631.682 If someone could do the calculation and i can compare the answers i have that would be a great help. thanks in advance Last edited by Gav33; May 21st 2014 at 04:14 PM.
