A solar collector has 8m of 10mm diameter copper tubing atta

A solar collector has 8m of 10mm diameter copper tubing attached to it. The collector (tube surface) is maintained at 350 K by solar irradiation. Water enters the tube at 300 K with a flow rate of 0.01 kg/s. What is the water exit temperature if fully developed flow is assumed? What is the total heat rate(W) of the solar collector (from tube surface to flowing water)? Was the fully developed assumption reasonable? (Determine if tube exit was in the developing region)

Solution

The answer of the following question is as follows .

The maximum temprarure of exit water is 230degree candidate

While the total heat rate is 67W.

These are solved values for the above given questions.
