In a concurrent-flow tubular heat exchanger, a liquid food, flowing in the inner pipe, is heated from 20 to 40°C. In the outer pipe the heating medium (water) cools from 90 to 50°C. The overall heat-transfer coefficient based on the inside diameter is 2000 W/(m² °C). The inside diameter is 5 cm and length of the heat exchanger is 10 m. The average specific heat of water is 4.181 kJ/(kg °C). Calculate the mass flow rate of water in the outer pipe.
