Answer:
The rate of heat loss from the pipe by convection is 433113 Btu/h
Explanation:
Given that:
The length of the steam pipe = 300 ft
Temperature of the open space = 50 ° F
Outside diameter = 4 ㏑ = 4/12 ft = 0.333 ft
Avg, temperature of the surface of the pie = 280° F
Avg. convection of heat transfer h = 6 Btu/h·ft²·°F
We are to Determine the rate of heat loss from the pipe by convection
Let first calculate the area of the heat transfer;
A = πdh
A = πdL
A = π× 0.333 ft ×300 ft
A = 313.85 ft²
The rate of heat loss from the pipe by convection can now be calculated by using the formula:
Replacing our values from above ; we have:
Therefore, the rate of heat loss from the pipe by convection is 433113 Btu/h
Answer:4050 W
Explanation:
Given
Heat transfer Coefficient(h)=
Air temperature =75 F
surface area(A)=
Temperature of hot tube is 102 F
We know heat transfer due to convection is given by
