3) Olive oil is cooled from 90°C to 20°C in a heat exchanger using water. Water enters the heat exchanger at 5 °C and exits at 25 °C. Densities of olive oil and water are 919 kg/m³ and 1000 kg/m³ respectively. Specific heats of olive oil and water are 2.01 kJ/(kg K) and 4.18 kJ/(kg K) respectively. Olive oil flows through a tube which has an internal diameter of 50 mm at a velocity of 1.54 m/s. What is the mass flow rate of water needed to cool the olive oil?
