Answer:
The required heat flux = 12682.268 W/m²
Explanation:
From the given information:
The initial = 25°C
The final = 75°C
The volume of the fluid = 0.2 m/s
The diameter of the steel tube = 12.7 mm = 0.0127 m
The fluid properties for density = 1000 kg/m³
The mass flow rate of the fluid can be calculated as:
To estimate the amount of the heat by using the expression:
q = 0.0253 × 4000(75-25)
q = 101.2 (50)
q = 5060 W
Finally, the required heat of the flux is determined by using the formula:
q" = 12682.268 W/m²
The required heat flux = 12682.268 W/m²
