Answer the question considering the information given in the picturea) Calculate the flow rate Q. Suppose you have an open tank with water like the one shown inFigure 1 whose area is very large compared to narrow areas, to this isadded a pressure gauge containing mercury and is open toatmospheric pressure. Know that the flow of water is constant and thatthe viscosity is negligible. Point C is open to the air and is where the|flow of Water comes out.2 m1mMercurio0,04 m0,05 mFigure 1.

A rotating viscometer consists of two concentric cylinders-a stationary inner cylinder of radius R, and an outer cylinder of inside radius Ro rotating at angular velocity (rotation rate) wo. In the tiny gap between the two cylinders is the fluid whose viscosity (u) is to be measured. The length of the cylinders (into the page in Figure 1) is L. L is large such that end effects are negligible (we can treat this as a two-dimensional problem). Torque (T) is required to rotate the outer cylinder at constant speed. Showing all your work and algebra, generate an approximate expression of T as a function of the other variables. Liquid: p, Ro Ri Stationary inner cylinder Rotating outer cylinder Figure 1 Wo

Check my we When measuring small pressure differences with a manometer, often one arm of the manometer is inclined to improve the accuracy of reading. (The pressure difference is still proportional to the vertical distance and not the actual length of the fluid along the tube) The air pressure in a circular duct is to be measured using a manometer whose open arm is inclined 45° from the horizontal, as shown in the figure The density of the liquid in the manometer is 0.79 kg/L and the vertical distance between the fluid levels in the two arms of the manometer is 12 cm. Determine the gage pressure of air in the duct and the length of the fluid.column in the inclined arm above the fluid level in the vertical arm.
