Liquid water with a specific heat of 4.18?kJ/kg•K is heated in a circular tube by an electrical heater at 10?kW. The water enters the tube at 10°C with a mass flow rate of 10?g/s. The inner surface of the tube is lined with polyvinylidene chloride (PVDC) lining. According to the ASME Code for Process Piping (ASME B31.3-2014, A323), the recommended maximum temperature for PVDC lining is 79°C. Determine whether the water exiting the tube would be in compliance with the ASME Code for Process Piping. What is the minimum mass flow rate of the water needed to keep the exit temperature from exceeding the recommended maximum temperature for PVDC lining?
