To convert to a decimal, divide by 100.
75 / 100 = .75
Change/original * 100
(72-42)/42 * 100
30/42 * 100 = .7143 *71.43 100 = 71%
Answer:
A
Step-by-step explanation:
Step-by-step explanation:
bananas are to be cooled from 24 to 138c at a rate of 215 kg/h by a refrigeration system. the power input to the refrigerator is 1.4 kw. determine the rate of cooling, in kj/ min, and the cop of the refrigerator. the specific heat of banana above freezing is 3.35 kj/kg·8c.
Evaluate the required thickness of styrofoam for the freezer compartment in the previous problem when the inside wall is exposed to air at −10 c through a surface coefficient of 16 w/m2⋅k and the outer wall is exposed to 33 c air with a surface coefficient of 32 w/m2 ⋅ k. determine the surface temperatures for this situation
