Q7 (50 pts) Free Respоnse Questiоn Oil flоws between pаrаllel plаtes 8 mm apart, as shown in the figure. A mercury manometer, with wall pressure taps 1 m apart, registers a 6-cm height as shown. Take the density of mercury as 13,600 kg/m3 and the density of the oil as 870 kg/m3. The width of the channel into the page is b = 0.75 m. a) Based on the manometer, estimate the pressure gradient, dp/dx, if x is in the flow direction. List any assumptions you make. b) Derive an expression that relates the volumetric flow rate, Q, to the pressure gradient dp/dx, the duct geometry, and the viscosity. List any assumptions you make. c) If the oil viscosity is
