An engineer is designing a very thin, horizontal channel for cooling electronic circuitry. The channel is 3 cm wide and 6 cm long. The distance between the plates is 0.4 mm. The average fluid velocity is 7 cm/s. The fluid used has a viscosity of 1.2 cp and a density of 800 kg/m³. Assuming no change in viscosity or density, find the pressure drop in the channel and the power required to move the flow through the channel.
