In a gear-driven exhaust fan and to improve the air flow, the speed of the fan needs to be increased to 460 rpm, but it must be as close to this speed as possible. the existing 3- hp motor will be used, which operates at 1750 rpm. the housing should not be altered, which has a bearing system with a center distance of 9.5 in. determine required diameters for the gears. (a) find the velocity ratio determine the pinion and gear diameters if motor gear has 22 teeth, find the diametral pitch pd and fan gear number of teeth (d) determine the output torque

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?
