Complete question is;
A hot plate with a temperature of 60 °C will be cooled by adding 50 triangular profile needle blades (k = 204 W/m.K) with a length of 54 mm and diameter 10 mm. According to the ambient temperature 20 °C and the heat transfer coefficient on the surface 20 W/m².K. Calculate,
a-) Wing efficiency
b-) Total heat transfer rate (W) from the wings,
c-) Calculate the effectiveness of a wing.
Answer:
A) Efficiency = 96.05 %
B) Total heat transfer rate = 166.68 W/m
C) Wing Effectiveness = 10.42
Explanation:
Please find attached explanation for all the answers given.
Answer:
1.The velocity of fluid
2.Fluid properties.
3.Projected area of object(geometry of the object).
Explanation:
Drag force:
Drag force is a frictional force which offered by fluid when a object is moving in it.Drag force try to oppose the motion of object when object is moving in a medium.
Drag force given as
So we can say that drag force depends on following properties
1.The velocity of fluid
2.Fluid properties.
3.Projected area of object(geometry of the object).
