Oil (SAE 30) at 15.6 C flows steadily between fixed, horizontal,parallel plates. The pressure drop per unit length along thechannel is 30 kPa/m, and the distance between the plates is4 mm. The flow is laminar. Determine: (a) the volume rate of flow(per meter of width), (b) the magnitude and direction of the shearingstress acting on the bottom plate, and (c) the velocity along thecenterline of the channel.
