3. A juice at a rate of 500 kg/h is heated from 60 °C to 115 °C. The juice has a specific heat of 3.85 kJ/(kg K). Steam at an absolute pressure of 202.7 kPa is used as the heating medium. Steam condenses and leaves the heat exchanger at 115 °C. Determine the mass flow rate of steam necessary to heat the juice.

**Problem 3: Heating Juice with Steam**

A juice is heated at a rate of 500 kg/h, increasing its temperature from 60 °C to 115 °C. The specific heat of the juice is 3.85 kJ/(kg·K). Steam, at an absolute pressure of 202.7 kPa, is employed as the heating medium. During this process, the steam condenses and exits the heat exchanger at 115 °C. Your task is to determine the mass flow rate of steam necessary to heat the juice.
