Answer:
Tso = 28.15°C
Explanation:
given data
t2 = 21 mm
ki = 0.026 W/m K
t1 = 9 mm
kp = 180 W/m K
length of the roof is L = 13 m
net solar radiation into the roof = 107 W/m²
temperature of the inner surface Ts,i = -4°C
air temperature is T[infinity] = 29°C
convective heat transfer coefficient h = 47 W/m² K
solution
As when energy on the outer surface at roof of a refrigerated truck that is balance as
Q = 
.....................1
Q = 
.....................2
now we compare both equation 1 and 2 and put here value
solve it and we get
Tso = 28.153113
so Tso = 28.15°C

It is made of cheap and easy to access parts.
Answer:
Orthographic projection is a projection method to present three-dimensional shapes in two-dimensional format in which the projection lines are drawn to be orthogonal to the plane of projection, such that each view of the three-dimensional object is translated to a view of the orthographic projection and orthogonal to the view
A multiview projection is the representation of a three-dimensional projection by two or more two-dimensional views
Explanation:
Answer:
One gallon of paint can cover about 400 square feet of wall.
18 x 15 feet is 270 feet of space.
270/400 = .675 gallons for one coat on one wall
.675 x 4 = 2.7 gallons for one coat on all walls
2.7 gallons x 2 = 5.4 gallons of paint in all
