Baby hamster kidney cells are immobilised in alginate beads. The average particle diameter is 5 mm. Rate of oxygen consumption at a bulk concentration of 8 x 10 ^-3 kg 0 2 m ^-3 is 8.4 x 10 ^-5 kg s^- 1 m^-3 catalyst. The effective diffusivity of oxygen in the beads is 1.88 x 10^ -9 m 2 s^- 1. Assume that the oxygen concentration at the surface of the catalyst is equal to the bulk concentration, and that oxygen uptake follows zero-order kinetics. calculate the observable Thiele modulus.

A stagnant liquid film of 0.4 mm thickness is held between two parallel plates. The top plate is maintained at 400C and the bottom plate is maintained at 300C. If

the thermal conductivity of the liquid is 0.14 W/(m K), then the steady state heat flux ( W/m²) assuming one-dimensional heat transfer is
