The ton of … WebCapacity = Mass Flow Rate x Specific Heat Capacity x Temperature Difference. Since the specific heat capacity is constant, the flow rate must be decreased in order to increase the temperature difference (delta T) while maintaining the same capacity. For every one delta T increase from 10°F (5.5°C), the water flow rate drops about 8% on average.
