There is a flow of air that circulates over a flat plate that is used to store a food product at a temperature of 95 ° C throughout its surface. The air flows at a speed of 2.5 m/s and has a temperature of 25.0°C. The plate measures 600.0 mm · 300.00 mm. As a task assigned by your plant operations manager, you are asked to answer the following questions: i. Determine the heat loss from the plate if the air flows parallel to the 600.00-mm side. ii. How would this heat loss be affected if the airflow is made parallel to the 300.0-mm side? For this type of configuration, the coefficient of heat transfer by forced convection, h, can be obtained from the relation IMAGE BELOW The previous correlation is valid for the laminar regime, that is: Re < 500000

Question
There is a flow of air that circulates over a flat plate that is used to store a food product at a temperature of 95 ° C throughout its surface. The air flows at a speed of 2.5 m/s and has a temperature of 25.0°C. The plate measures 600.0 mm · 300.00 mm.
As a task assigned by your plant operations manager, you are asked to answer the following questions:
i. Determine the heat loss from the plate if the air flows parallel to the 600.00-mm side.
ii. How would this heat loss be affected if the airflow is made parallel to the 300.0-mm side?
For this type of configuration, the coefficient of heat transfer by forced convection, h, can be obtained from the relation
