What is the Product Load (QP)?

• The total weight of the product

• The heat that must be removed from the product

• The heat that must be added to the product

• The temperature of the product

Which factor does NOT affect the Product Load?

• Temperature at which the product enters the refrigerated room

• Type of Product

• Quantity of Product

• Color of Product

What is the formula for calculating Sensible Heat Above Freezing (QSAF)?

• QSAF = Mass × Specific Heat

• QSAF = Mass × Latent Heat

• QSAF = Mass × Specific Heat × Temperature Difference

• QSAF = Mass × Temperature Difference

If 1000 lbs of lettuce enters the cooler at 75 °F and the cooler’s temperature is 38 °F, what is the sensible heat removed?

• 6000 Btu

• 35520 Btu

• 48000 Btu

• 12000 Btu

What does QSBF represent?

• Sensible heat of the product above freezing

• Latent heat of fusion

• Sensible heat of the product below freezing

• Heat of respiration

What is the specific heat value for lean beef below its freezing point?

• 0.40 Btu/(lb °F)

• 0.96 Btu/(lb °F)

• 0.50 Btu/(lb °F)

• 0.75 Btu/(lb °F)

How is the Latent Heat of Fusion (QLH) calculated?

• QLH = Mass × Latent Heat

• QLH = Mass × Specific Heat

• QLH = Mass × Heat of Respiration

• QLH = Mass × Temperature Difference

What is the heat of respiration (QR)?

• Heat added to maintain temperature

• Heat that must be removed to cool a product

• Heat required to freeze a product

• Heat given off by vegetables/fruits after harvest

If 1500 lbs of corn has a heat of respiration of 11500 Btu/Day/Ton, what is the QR for this corn?

• 15000 Btu/Day

• 11500 Btu/Day

• 7500 Btu/Day

• 8625 Btu/Day

What is the freezing point of bananas according to the text?

• 25.0 °F

• 28.0 °F

• 30.0 °F

• 32.0 °F
