Answer:
For aluminum 110.53 C
For copper 110.32 C
Explanation:
Heat transmission through a plate (considering it as an infinite plate, as in omitting the effects at the borders) follows this equation:
Where
q: heat transferred
k: conduction coeficient
A: surface area
th: hot temperature
tc: cold temperature
d: thickness of the plate
Rearranging the terms:
d * q = k * A * (th - tc)
The surface area is:
If the pan is aluminum:
If the pan is copper:
Answer:

Answer
diameter of parking lot = 18 in
flowrate = 10 ft³/s
pressure drop = 100 ft
using general equation
taking f = 0.0185
at Z₁ = Z₂
ΔP = 0.266 psi
b) when flow is uphill z₂-z₁ = 2
c) When flow is downhill z₂-z₁ = -2
