Question 72General Subjects - 1st Asst/Chief

The correct answer is A) The absolute pressure of the unit would increase, causing a decrease in distillate output. If valve "25" vibrates open while the unit is in operation, it would allow air to enter the system, increasing the absolute pressure within the distiller. This increased pressure would result in a lower pressure differential across the distiller, leading to a decrease in the distillate output. The other options are incorrect because: B) The unit would not automatically shut down due to low pressure contacts, as the increased pressure would not trigger a low-pressure condition. C) The jacket water would not be automatically bypassed, as this would not be the appropriate response to the increased pressure. D) The unit would not continue to operate without adverse effects, as the decreased distillate output would be an adverse effect.
