To determine the amount of cooling water<\/strong><\/span><\/p>\n<p><span style=\"font-family:Arial;\">To calculate the amount of cooling water, five factors should be considered: the calorific value of the engine under standard operating conditions, the calorific value of the maximum operating conditions, the proportion of heat taken away by cooling water and engine oil, the number of test rooms, and the total cooling efficiency and loss.<\/span><\/p>\n<p><span style=\"font-family:Arial;\"><strong>2.

The flow of the pumps is adjusted by the amount of water required for the engine bench test, and the operation is controlled automatically.
