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
It is a linear equation with only one unknown, although it looks strange because of the fractions, so lets get rid of the fractions:
<span>2/x = 1/4
</span>(2/x) = (<span>1/4)
</span>4*(2/x) = <span>1
8/x = 1
8 = 1*x
x = 8
that is the solution</span>
The product of a negative number and a positive number is always negative.
Here's something funny my math teacher once told us to help us remember.
Good thing happening to a Good person = Good
positive x positive = positive
Bad thing happening to a Good person = Bad
negative x positive = negative
Good thing happening to a Bad person = Bad
positive x negative = negative
Bad thing happening to a Bad person = Good
negative x negative = positive
