Hot air at 400°C and 150 kPa is to be used to produce saturated steam at 200°C in an insulated, non-mixing heat exchanger. Water enters the heat exchanger at 20°C while the air leaves at 350°C. The mass flow rate of air is 0.8 kg/s, pressure drops are negligible, and specific heats for air are evaluated at the average air temperature. What is the mass flow rate of water, in kg/s. Report your answer to four decimal places using rounding.

How much heat must be supplied to water at 180 degrees celcius to make 1 kg of wet steam at 9000 kpa , having a dryness fraction of 80% ?. I was given this as an answer ;but dont know where they found the enthalpy at a 180 degrees in steam table , and dont know how they got 163 for h1 at then end equation to calculate heat ? given; mass,m=1 kg temperature , t =180 degrees celcius pressure,p=9000kpa find q solution: from steam table at 180 degrees celcius , the enthalpy , hf=h10103 kj/kg from the steam table at 9000 kpa hf=763.22 hfg=1378.9 therefore : h2=hf + x (hfg) =763.22 +0.8(1378.9) =1866 kj/kg calculate heat required: q=h2-h1=1866-163=1703
