A flat-plate heat exchanger operates in a nitrogen atmosphere at a pressure of about 10 4 N/m

Question:

A flat-plate heat exchanger operates in a nitrogen atmosphere at a pressure of about 104 N/m2 and 38°C. The flat-plate heat exchanger was originally designed to operate in air at 1 atm and 38°C turbulent flow. Estimate the ratio of the heat transfer coefficient in air to that in nitrogen, assuming forced circulation cooling of the flat-plate surface at the same velocity in both cases.
