Water at 68°f flows at 100 gal/min through a 2 inch inside diameter commercial steel pipe that is 150 ft long. the fanning friction factor for this system is 0.00526. how many standard 90° elbows can be added to the system before the overall pressure drop exceeds 25 psi?

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Have a greater impact on maintenance productivity than any other support group. (clo5) a)-the top management b)-inventory and purchasing c)-sub-contracting d)-cmms
