1.Water is flowing in a 6-cm diameter pipe at 20 m/s at 10?C. If the pipe enlarges to a diameter of 12-cm, calculate the reduced velocity. Also, calculate the mass flux rate and the flow rate.

2.A rectangular gate is inclined at an angle of 30 degrees from the horizontal. It is 4 ft wide by 6 feet long. If it is hung from its upper end which is 8 feet below the waters top edge, what minimum applied force (bottom) is needed to open the gate?

3.The blades of the portable fan generate a 1 lb thrust T as shown. (h = 8 in.) Compute the moment MO of this force about the rear support point O. For comparison, determine the moment about O due to the weight of the motor-fan unit AB, whose weight of 12 lb acts at G.

4.During a drilling operation, the small robotic device is subjected to an (F =) 900 N force at point C as shown. (? = 25°.) Replace this force by an equivalent force-couple system at point O.
