In a manufacturing plant that produces cosmetic products, glycerin is being heated by flowing through a 25-mm-diameter and 20-m-long tube. with a mass flow rate of 0.5 kg/s, the flow of glycerin enters the tube at 25°c. the tube surface is maintained at a constant surface temperature of 140°c. evaluate the properties for glycerin at 30°c.

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only

answer:

d. attempt to find the owner, then leave your information if you cannot find them.

explanation:

d. represents both (b) and (c).

more logical as well.

b and c are to complicated.

glad i could , give me a follow, so if you need with any other question, im here.
