Well, if it were perfect, cooling time would be infinite, wouldn't it? To calculate the rate of temperature rise you need to know the amount of water, the rate at which heat is input and the rate at which heat is lost from the body of water. An example is cooling of a cup of tea. Newton's Law of Cooling Calculator: T : T is the constant temperature of the surrounding medium. The amount of evaporated water can be expressed as: g s = Θ A (x s - x) / 3600 (1) or . Tbatchavg = the average temperature of the batch liquid, expressed as deg F. This will be used as the temperature for determining the physical properties.
