1.A 6 in orifice is placed in a 10 in pipe and a mercury manometer is connected to either side of the orifice. If a flow rate of water (60 F) through this orifice is 3 cfs, what will be the manometer deflection?
2.What size of orifice is needed to produce a change in head of 9m for a discharge of 2 m^3/s of water in a 1-m diameter pipe.
3.The pressure inside a 4 cm hose is 700 kPa. If the water exits through a 2 cm diameter nozzle, what velocity in m/s, can be expected inside the hose ?
