A pressurized fluidized-bed reactor operates at 10.0 MPa and 260℃. The core contains TRISO fuel particles have a 1.1 cm diameter and a density of 10.2 g/cm3. The pressure drop in the collapsed state is found to be 27 kPa, and the pressure drop in the fluidized state is found to be 41 kPa. The diameter of the core measures 2.0 meters. Determine:

(a) the height of the core in the collapsed state

(b) the height of the core in the fluidized state

(c) the void fraction in the fluidized state

(d) the water-to-fuel volume ratio in the fluidized state

(e) the minimum fluid velocity needed to suspend the fuel

(f) the convective heat transfer coefficient, ℎ, associated with the coolant
