Question 26

An industrial heater transfers energy at a rate of 4.8 kW to a liquid passing through it. The liquid has a specific heat capacity of 4.0 kJ kg-1K-1. When the liquid flows through the heater, its temperature increases by 8.0 K. What is the flow rate of the liquid?

0.15 kg s−10.15\text{ kg s}^{-1}0.15 kg s−1

1.5 kg s−11.5\text{ kg s}^{-1}1.5 kg s−1

9.6 kg s−19.6\text{ kg s}^{-1}9.6 kg s−1

150 kg s−1150\text{ kg s}^{-1}150 kg s−1
