Dec 29, 2018 This converts the volumetric flow rate to a mass flow rate, which is measured in pounds of water per hour. With this example: 3,900 x 500 = 1,950,000. This answer is the chiller's capacity measured in BTUs per hour. Divide your answer by 12,000: 1,950,000 / 12,000 = 162.5. This is the chiller's capacity in tons.
