1- The following values are for saturated steam at 508.15K. Show that the liquid and vapor states of water are in equilibrium. 2- Complete the following table without using the steam table: Use T(K)=T(C)+273.15. (Answer: T=135C,HV=2795.9kJ/kg,SL=3.6594kJ/kgK ). 3- The vapor pressure of water as a function of temperature is given by lnPH2Ovap=13.8365T6.6075103+T210.1855105T317.7039107,300T600, where PH2Ovap is in bar and T is in K. (a) Estimate the minimum pressure at which water exists as a liquid at 350K. (b) Estimate the maximum pressure at which water exists as a vapor at 500K. (Answer: (a) 0.425 bar and (b) 26.56 bar)
