Document Summary
Midterm 1: 5000 gmole/h of air is heated from 25 to 300 in a heat exchanger. The heat comes from the water vapor 315 and 1 mpa. The steam leaving has a quality of 0. 1 and a pressure of 1 mpa. What is the temperature of the steam leaving: a heater is used to increase the concentration of sugar in maple syrup. At the beginning there were 500 lbs of syrup in the heater and the mass fraction of the sugar (c12h12o11) in the syrup was 0. 01. The flow rate of the water exiting is 25 lbs/h. Write the differential equation expressing the transition region. How long (in hours) will it take for the mass fraction to reach a value of 0. 1: a liquid mixture is composed of 50% ni (co) 4 and fe (co) 5. Ni + 4 co = ni (co) 4 boiling point of ni (co) 4 = 43.
