Q8:- Saturated steam at 300 'C (density= 0.38Kgim') is Used to heat a COunter currently flowing stream of methanol vapor from 65 'C to 260 °C in an adiabatic heat exchanger. The flow rate of the methanol is 5500 liters per minute at latm (ideal gas), and the steam condenses and leaves the heat exchanger as liquid water at 90 "C. Calculate the required flow rate of the entering steam in m' /min. Calculate the rate of heat transfer from the water to the methanol in (KJ). Given that Cpetlano = 42.93+0.08301T (J/Kmol."C), R (Gas constant = 0.08206 atm. Iter /gmol.K), Cpsteam= 5.980 KJ/Kg.K, Cpm liçuid water=4.205 KJ/Kg.K, A.ater=2257 KJ'Kg Tx=Te+273.
