A 0.1 cm thick flat copper plate, 2.5 m x 2.5 m square is to be cooled

Question:

A 0.1 cm thick flat copper plate, 2.5 m x 2.5 m square is to be cooled in a vertical position. The initial temperature of the plate is 90?C with the ambient fluid at 30?C. The fluid medium is either atmospheric air or water.(a) Calculate the Grashof numbers(b) Determine the initial heat transfer coefficient(c) Calculate the initial rate of heat transfer by convection(d) Estimate the initial rate of temperature change for the plateGIVENA vertical flat copper plate in either air or waterPlate thickness (t) = 0.1 cm = 0.001 mPlate dimensions (L x w) = 2.5 m x 2.5 mInitial plate temperature (Ts,i) = 90?CAmbient fluid temperature (T??) =30?C
