Question
Classify the following descriptions as batch, continuous, or semibatch processes. Process A: You take jigsaw puzzle pieces one at a time from a full box until the box is empty. Process B: A faucet wasn't turned off all the way in the kitchen sink. A small stream of water falls into a cup that is running over. Process C: water is poured in an ice cube tray, placed in the freezes, and is removed from the ice cube tray. Process D: You make coolies by mixing butter and sugar together, adding an egg, then adding flour, salt, baking soda, baking powder. After mixing for 2 minutes, you stir in chocolate chips. Finally you drop the batter on to cookie sheets. Process E: A hairdryer sucks in air from a room, and blows out heated air from a nozzle.Explanation / Answer
Process A is semibatch because jigsaw pieces are removed from the box but not placed back into the box.
Process B is a continuous process because water flows into and out of the cup constantly.
Process C is a batch process because the water is charged into the ice cube tray, and no other mass enters or exists the ice cube trays until the ice cubes are frozen.
Process D is a semibatch process because mass is added to the process at several stages during mixing, not continuously.
Process E is a continuous process because air enters and leaves the hairdryer constantly.
