Question

2. a fluid of thermal conductivity 0.5 w/m-??c flows past a surface. the heat transfer coefficient has been measured to be 45 w/m2-??c when the surface temperature is 70 ??c and the fluid temperature far away from the surface is 25 ??c. what is the heat flux at the surface? what is the temperature gradient within the fluid normal to the surface
