Question 352Motor Plants - Assistant Engineer
70% to passExcess brine accumulated in the distiller, shown in the illustration, is removed during normal operation by_______________. Illustration MO-0111
Aopening the drain valve located to the left of orifice "19"
Borifice "19" regulating the amount of feedwater entering the distiller, thereby preventing excess brine accumulation
Cthe hydrokineter labeled "21"
Dthe continuous action of ejector "22"
AI Explanation
The correct answer is D) the continuous action of ejector "22". The illustration shows a distiller system, and in normal operation, excess brine is continuously removed by the action of the ejector labeled "22". The ejector uses the principle of the Venturi effect to create suction and draw the excess brine out of the distiller, preventing it from accumulating. This is the intended method for removing excess brine during regular operation. The other options are incorrect because: A) opening a drain valve is not the normal method for removing excess brine, B) orifice "19" regulates feedwater, not brine removal, and C) the hydrokineter labeled "21" is for measuring the density of the brine, not removing it.
