1. A three effect evaporator uses original steam at a saturation pressure of 174.4kPa gauge. The total boiling point rise is 8.3° K in the first effect, 13.9° K in the second effect and 22.2° K in the third effect. The limiting pressure which must be maintained in the vapor space of the third effect in order for the evaporator to operate is a. 60.7kPa e. none of the above 68.7 kPa b. 58.5kPa 50.7 kPa c. d.
