Answer:
a) The exit temperature is 39.25°C
b) The highest component surface is 132.22°C
c) The average temperature for air equal to 35°C is a good assumption because the air temperature at the inlet will increase due to the result in the heat gain produced by the duct and whose surface is exposed to a flow of hot.
Explanation:
a) The properties of the air at 35°C:
p = density = 1.145 kg/m³
v = 1.655x10⁻⁵m²/s
k = 0.02625 W/m°C
Pr = 0.7268
cp = 1007 J/kg°C
a) The mass flow rate of air is equal to:

The exit temperature is:
°C
b) The mean fluid velocity is:

The hydraulic diameter is:

The Reynold´s number is:

Assuming fully developed turbulent flow, the Nusselt number is:


The highest component surface temperature is:
°C
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Answer:
Quadrants are counter-clockwise because angles are measured counter-clockwise; and angles are measured counter-clockwise so that Cross Product of unit vector in X direction with that in the Y direction has to be the unit vector in the Z direction (coming towards us from the origin).
Explanation:
The total present worth is $19,783.01
The present worth of a series of cash flow is the value of the cash flows in year 0 (today)
Cash flow in year 0 = 5330
Cash flow in year 1 = 0
Cash flow in year 2 = 0
Cash flow in year 3 = 13075 / (1.02)^3 = 12,320.86
Cash flow in year 4 = 2308 / (1.02)^4 = 2,132.24
Present worth = $19,783.01
