A horizontal pipe of diameter 0.768 m has a smooth constriction to a section of diameter 0.4608 m. The density of oil flowing in the pipe is 821 kg/m3 . If the pressure in the pipe is 7120 N/m2 and in the constricted section is 5340 N/m2 , what is the rate at which oil is flowing? Answer in units of m3/s.

A venturi is a pipe-like device with a smooth internal constriction, as shown below. Air flows (20 pts) through a particular venturi, entering with know velocity (V~ ), temperature (T), and pressure (P). The venturi starts with a diameter (D), and constricts to a smaller diameter (d). A small barometer-like tube is attached to the venturi at its constriction, and filled with oil of known density (?oil). Answer the following questions about this system using the information in data table....

The feasibility of constructing a profitable electricity producing windmill depends on the mean velocity of the wind. For a certain type of windmill, the mean would have to exceed 20 miles per hour to warrant its construction. The determination of a site's feasibility is a two-stage process. In the first stage, readings of the wind velocity are taken and the mean is calculated. The test is designed to answer the question, " is the site feasible?" In other words, is...

The velocity profile for a steady laminar flow in a circular pipe of radius R is given by u=u0(1−r2R2) . If the fluid density varies with radial distance r from the centerline as ρ=ρ0(1+rR)14 , where ρ0 is the fluid density at the pipe center, obtain and choose the correct relation for the bulk fluid density in the tube.
