Q2 Which of the following statements is true for compressible flow in a packed bed of spheres?

	A.	Mass flow varies as you travel downstream through the bed
	B.	Superficial velocity must remain a constant throughout the bed due to conservation of mass
	C.	The friction factor is a function of position
	D.	Superficial velocity at the outlet of the bed is lower than the superficial velocity at the inlet
