Estimate the convection heat flow to a 2.0 m high and 1.2 m wide glass window. The average inside surface temperature is 5 °C. Room air temperature is 25 °C. 

 

2. Though it may be classified as a rather simple mistake, a frequent cause for substantial error in convection calculations is failure to select the correct geometry for the problem. Consider the following geometries for flow of air at 1 ATM, 300 K and a Reynolds number of 50,000. Calculate the average heat-transfer coefficient for each of these geometries and comment on the results
