To calculate a rate of flow, the concentration of ice water at each instant must be determined. For now, assume that the room temperature of the water was around 24° C. Two known concentration levels are: (1) when there is no ice water and (2) when there is 100% ice water. Recall that ice water is used since the temperature is known to be approximately 0° C.

Think about the following diagram.What do you think the measured temperature will be when the concentration is 50% ice water (half ice water and half room temperature water)?
