Question 76General Subjects - 1st Asst/Chief

The correct answer is D) the absolute pressure of the unit will increase with an associated increase in shell temperature. When valve "H" is opened wide while the distiller is in operation, it allows more air to enter the distiller unit. This increased airflow will result in an increase in the absolute pressure within the distiller, as more air is introduced into the system. The increased pressure will also lead to an increase in the shell temperature of the distiller, as the higher pressure environment causes the steam to condense at a higher temperature. The other options are incorrect because: A) the pressure would increase, not decrease, B) the air ejector is not the primary factor affecting pressure in this scenario, and C) the pressure would increase, not remain unaffected.
