The air, which has a temperature of 120 ° C, flows
over a plate with a length of 1.2 m and a constant temperature of
30 ° C across the surface, and its speed flows at a speed of 2 m /
s. According to this,
a.) Calculate the speed and temperature boundary layer thickness at
the end of the plate.
b.) Find the local heat transfer coefficient and heat flux at the
end of the plate.
c.) Find the average heat transfer coefficient and heat flux at the
end of the plate.
(Properties of the air will be taken from the table)
