Prove that the area of an irregular parcel land enclosed by curvilinear figure can be used to compute the are of a plot of computed using the formula below .Area=×\3(×_2Q+4E).the working using Simpson rule in survey

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
