A particular soil sample is subjected to test for the determination of permeability coefficient in two separate constant head permeameters, whose specifications are as under:

	Permeameter	Permeameter
	A	B
Diameter of sample	D	2D
Length of  sample	2L	L

If the tests on both the permeameters are conduced with equal head of water applied on the samples, then the ratio of amount of water discharged through the permeameters A & B during a period of one hour will be:
