1.The specific enthalpy of water at 5.0 bars and a specific volume of 100 cm3/gr is approximately ____________kJ/kg

2.The specific enthalpy of water at 5.0 bar and 60 oC is approximately  ______________ kJ/kg

3.1 kg/s of steam at 2.0 bars enters a heat exchanger (see figure) as saturated vapor and leaves as saturated liquid.  Heat from the     steam is taken up by a coolant liquid (Cp = 5.0 kJ/kg K) which enters at 25 oC and leaves at 40 oC.  The required flow rate of the coolant is_________ kg/s

4.Saturated liquid water at 10 bars is expanded through an adiabatic             valve at steady state to a pressure of 2.0  bars.  The amount of entropy creation per unit mass  is ________kJ/kg K
5.       A closed, rigid vessel originally contains 1 kg of saturated liquid water and 1 kg of saturated vapor water at a pressure of 100 bars.  Heat is added until the final pressure in the vessel is 150 bars.  The amount of heat added is _________KJ
