(a)

To determine

The heat fluxes associated with convection, ${q^{″}}_{conv}$ , evaporation ${q^{″}}_{evap}$ and radiation exchange with the sky ${q^{″}}_{rad}$ .

(b)

To determine

The reason that the calculation suggests the concrete is wet instead of dry with explanation.

(c)

To determine

Whether the heat is flowing from the liquid layer to the concrete, or from the concrete to the liquid layer and also the heat flux by conduction into or out of the concrete.
