Air at 10 atm and 25°c flows with free stream velocity of 6 m/s over a flat plate at 75°c. deter- mine the heat flux at 0.05 m intervals upto a distance where the reynolds number is 5 x 10^5.

Explanation:

Given that velocity=6 m/s

Temperature of surface=75 °C

Temperature of air=25 °C

Reynolds number =

It means that this is laminar flow.So Nusselt equation given as follows

Now properties of air at mean temperature of 75 °C and 25 °C (50 °C) is taken from standard table

K=0.028 W/m-K,Pr=0.71

And we also know that

Now by putting the values

Nu=406.24

So heat flux q= hΔT

q=227.49  x (75-25)

this is true

i looked it up

the clapeyron equation (also called the clausius-clapeyron equation) relates the slope of a reaction line on a phase diagram to fundamental thermodynamic properties.
