Solid food particles having nominal size of $0.2 \mathrm{~mm}$ with shape factor of 0.8 and density of $1040 \mathrm{~kg} \mathrm{~m}^{-3}$ are to be fluidized using air at $28^{\circ} \mathrm{C}$. The density and pressure of air at the above-mentioned condition are $1.175 \mathrm{~kg} \mathrm{~m}^{-3}$ and $1.013 \times 10^{5} \mathrm{~Pa}$, respectively. The voidage at minimum fluidizing condition is 0.48 . Use the value of 'g' as $9.81 \mathrm{~m} \mathrm{~s}^{-2} .$ If cross section of the empty bed is $0.5 \mathrm{~m}^{2}$ and contains $520 \mathrm{~kg}$ of solids, the pressure drop at minimum fluidization condition is____kPa
