A packed bed reactor is filled with catalyst material with a diameter of 2.5 mm. The length of the reactor is 75 cm and the catalyst has a porosity of 0.55. The superficial mass velocity of the inlet gas is 16 kg/m2-s with a viscosity of 1.55x10-5 kg/m-s and a density of 2.6 kg/m3. The inlet pressure is 1000 kPa. Find the pressure, P, at the end (the exit) of the PBR. Express your answer in kPa to the
