• A 1.8 [m] drainage conduit is shown in the figure. The pipe is half full of water at rest. • Determine the magnitude and line of action (to AC) of the resultant force that the water exerts on a 0.3 [m] length of the curved section of BC of the conduit wall.

Consider the pipe structure projecting from the wall at point “A”. Find the resultant force and couple moment acting at point “A”.   Express the resultant force and couple moment in Cartesian (vector) form.  (Hint: the 1,000 lb force needs to be expressed as a vector and the “dimension box” provides the information necessary to define the unit vector in the direction of F.)

A turbine with a power coefficient Cp = 0.28 is able to generate 2.1 MW of electrical power with blades of length R =75 m. What is the value of the wind speed? Calculate the value in meters/second and round off to two decimal places. Do not write the unit.
