Question

You must design a pump system to have 10 channels in parallel. The pump has the following limitations:

1) it could only generate a pressure difference of 20,000 dynes/cm2 ,

2) It could only generate a maximum flow rate of 10 ml/hr.

Determine how tall they should have made the channels (which had a rectangular cross section) given the following restrictions:

A) the channels were 20 times wider than the height, so that no edge effects would be included.

B) The viscosity and density of the circulating media was .008 g/cm/s and 1 g/ml, respectively.

C) The surface shear stress cannot be above 1 dyne/cm2 ; otherwise the cells would rupture.

D) The channels were all 6 cm long.

Theanswer of the following question is as follows

They should have made the channel 40 cm
