A diffuser is integrated into a system. Superheated water vapor enters the diffuser at a temperature of 473.15K and a pressure of 10 bars. The incoming velocity of the vapor is 100 m/s and exits at 30 m/s. The inlet diameter of the diffuser is 40 cm. At the exit of the diffuser, the pressure of the saturated vapor is 3 bars. The exit area (in square meters) of the diffuser is: O 3.333 O 1.232 O 0.102 O Cannot be determined with the information provided

In a spur gear arrangement, the driver has 80 teeth of 39 mm pitch. Find the power, if it can transmit a tangential force of 60 N. Take speed of driver as 150 rev/min. Insert your answer for power in watt correct up to at least a third decimal place.

The diagram below shows a shaft with spur gear (B), bevel gear(D), and two supporting bearings (A and C). All dimensions are in millimeters and all shoulder fillets (at points where diameter changes) have a radius of . The pressure angle for the spur gear at B is . The pressure angle for the bevel gear at D is  and the bevel angle is . Note that the shaft is designed so that only bearing A takes thrust. The shaft is made of steel with . All the critical surfaces are ground. The shaft rotates at . A motor with a power of  is connected at the bevel gear through another bevel gear. This drives the shaft. A load is connected through another spur gear at the output spur gear at B. The standard deviation on the power is . (a) Determine the forces acting on the gears. Recall that for a spur gear, the relation between the tangential component of the force and the radial component of the force and the pressure angle is given by . For this bevel gear, the axial (thrust) component of the force on…

Find the greatest and smallest values of the velocity ratio of two shafts joined with a universal coupling when the axes are at 60o to each other. Produce a graph of velocity ratio against angle for f to proof the calculated results.
