Question
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?
