Hi Andrew, How do you get from 6300KJ to mWs? If 1 kW is equal to 3,600KJ, how do you then convert that to mW? Also, do you not require 20.3KJ to raise the temperature of -5°C ice to 0, then the 688.3KJ to change state to water? Or is it solely the 688.3KJ to go from ice at -5 to water at 0...

Hello Andrew, Thank you for the quick reply. The scenario is based upon a plate heat exchanger which has a coating of ice over it. Heated water from a buffer vessel will pass through the heat exchanger in a bid to defrost the formed ice. The 7 minutes was calculated by...

Hi All, New to the forum, but requiring a certain amount of assistance if possible. In relation to ice defrost time, 334 Joules per gram is required to change the state of ice to water and 2.03 joules per gram is required to raise the temperature of ice by one degree? With this in...
