Discuss the below in detail:
Q: A large 2.54-cm.-thick copper plate is placed between two air streams. The heat transfer coefficient on the one side is 28 W/(m2 K) and on the other side is 57 W/(m2 K). If the temperature of both streams is suddenly changed from 38°C to 93°C, determine how long it will take for the copper plate to reach a temperature of 82°C.
GIVEN
A large copper plate between two air streams whose temperatures suddenly change
Plate thickness (2L) = 2.54 cm = 0.0254 m
The heat transfer coefficients are hcl = 28 W/(m2 K)
hc2 = 57 W/(m2 K)
Air temperature changes from 38°C to 93°C
ASSUMPTIONS
The initial temperature of the plate is 38°C
The plate can be treated as an infiniteslab
