In a constant head permeability test the coefficient of permeability, k, was found to be 2.1 x 10-3 m/s. Determine the head measured over a length of the flow of 140 mm, if the sample has a diameter of 100 mm and the flow rate, q, of 150 ml/min.

In a constant head permeability test the coefficient of permeability, k, was found to be 2.1 x 10-3 m/s. Determine the head measured over a length of the flow of 140 mm, if the sample has a diameter of 100 mm and the flow rate, q, of 150 ml/min.
Hint - rearrange the formula used to find k in a constant head test. Convert all values into the same units - i.e. ml/min to mm3/s.
