**Understanding Heat Transfer in Cross Flow**To study the heat transfer from a bar in cross flow, a series of experiments were conducted to measure the average heat transfer coefficient (\(\bar{h}\)) as a function of the free stream velocity (\(V\)). The schematic of the experiment and results are below:**Experimental Data:**- \(\bar{h}\) [W/m²-K] | \(V\) [m/s] - 60 | 20 - 40 | 15**Schematic:**- Represents a bar with a length of \(L = 0.3 \, \text{m}\) in cross flow, depicted with airflow striking the bar.**Questions:**a) The important dimensionless parameters are related by the form:\[\bar{Nu} = C \text{Re}_L^m \text{Pr}^n\]where \(C\), \(m\), and \(n\) are constants. The film temperature in both experiments is approximately the same. Use the experimental results to determine the constant \(m\).b) Calculate \(\bar{h}\) for \(L = 0.75 \, \text{m}\) and \(V = 30 \, \text{m/s}\).

Given:To find:(a) Value of constant m.(b) Value of .
