When orange juice is produced it must be heated to pasteurize it. This is achieved by passing the juice through a tubular heat exchanger. The juice must be heated from 4oC to 93 oC. Saturated vapor enters the outer tube of the heat exchanger at 150 kPa and exits as a saturated liquid at the same pressure. For an orange juice flow rate of 2000 kg/hr (cp = 3.9 kJ/kg K), determine the required steam flow rate.
