Chf & Dry Cough & Vomiting Heat Loss Calculation In Pipe?

Heat loss calculation in pipe? - chf & dry cough & vomiting

Hello ...

I'm not the problem and should be used to the heat loss through the tube to be calculated.

During the drying of rice, the heat needed to dry the rice. We use the shell as a fuel burned in the oven to dry heat provide cyclone. But is along the heat pipe, there is no insulation was installed in the pipe. Therefore, I am, want to know how much heat is lost from CHF in the dryer. In particular, the equation that I found you need the temperature in the pipe and the surface temperature of the tube. But I have the information from the temperature at the inlet and outlet pipe or tube.

Can anyone help?

You ask, sounds like you have no idea what we demand, and provides little information to make estimates.

If you heat the air, and if you know the entry and exit time, and if you know the flow of air must be able to calculate the heat loss.

To calculate the heat loss through the pipes, the surface temperature, wind speed and temperature and size of the tube. Since these parameters are the minimum requirements that must be available.
Of course, in the absence of data, we can always make assumptions.
I suggest the following assumptions, then repeat the calculation, if necessary.
Assumptions:
The wind speed of 2 m / s
Temperature 28 C
Take the average temperature at the surface of the input / output (conservative). If the flow is turbulent in the pipe, the surface should be closer to the temperature of the liquid to the heat loss would be the coefficient of heat transfer in the tube is larger than the tube to overestimate the outside.
