What would happen if valve "25" shown in the illustration, vibrated open with the unit in operation? Illustration MO-0111
AI Explanation
The correct answer is C) The absolute pressure of the unit would increase, causing a decrease in distillate output.
If valve "25" shown in the illustration vibrated open with the unit in operation, it would cause a loss of pressure in the system. This increased absolute pressure within the distiller would result in a decrease in the distillate output, as the higher pressure would make it more difficult for the water vapor to be expelled from the unit. The other options are incorrect because the unit would not continue to operate normally (A), there is no low-pressure shutdown mechanism described (B), and the jacket water would not be automatically bypassed (D) due to the pressure increase caused by the open valve.
