Question

Table 1 shows the physical properties of coolant at 300oC in the channel of a PWR nuclear reactor.
Figure 1 shows a typical square lattice of the coolant channel within the fuel rods with rod pitch,
S and rod diameter, D. From the given data and using the non-dimensional parameters such as
Reynolds number (Re), Prandtl number (Pr) and Nusselt number (Nu), evaluate the convective
heat transfer coefficient, hc of the coolant during cooling
