Water is stored in a tank which has vent open to the atmosphere. the water level is 1.0 m below the top the tank and the water is 4 m deep. a siphon with .03 m id is used to remove water from the tank. the siphon discharge is 6.0 m below the top of the tank. neglect the friction loss of water through the siphon. determine the flow rate of water in unit of m^3/s.

Asimple speed reducer is composed of 2 spur gears. the pinion gear has a pitch diameter of 0.75" and 36 teeth while the driven gear has a pitch diameter of 4.0" and 192 teeth. a)-what is the diametral pitch of each gear? b)-if an electric motor rotating ccw at 3000 rpm is coupled to the pinion, what is the rotational speed of the driven gear? c)-if the torque delivered to the pinion is 1 n-m, what is the torque on the driven gear? d)-what is the power transmitted by the gear train?
