Water passes through a centrifugal pump impeller of 0.6 m outlet diameter and 0.4 m inlet diameter. the impeller is ro with respect to the tangential direction. the fluid enters radially with velocity of flow of 10 m/s and there is a constant radial flow through the device. the ideal head imparted to the fluid (in m) is a)-8.78 b)-3.34 c)-27.44 d)-5.28

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
