Extracted text: 1.Convert 21 inches of Hg (vacuum, gauge) to kPa (absolute) 2. Trays which hold 10 ounces are being processed in a continuous retort. The cook zone of the retort is 120 inches long. The belt speed is 2.1 feet per minute. If the trays are 5 inches wide and spaced 1 inch apart on the belt, what is the production rate of the system in trays per hour? What is the production rate in kg per hour? What is the exposure time of a tray in the cooking zone in minutes? 3. A differential pressure sensor is attached across the two effects in an evaporator reads 5.6 psi with the high side attached to the first effect. A separate gauge on the first effect reads 9.21 inches Hg (vacuum). What are the pressures of the first and second effects in kPa absolute?
