1. If the pump removes 12 ft /min of water from a tank, how long will it take to empty the tank if it contains 20000 lb of seawater @ 25°C? 2. A standard schedule 40 steel pipe is to be selected to carry 10 gal/min of water with a maximum velocity of 1 ft/s. what size pipe should be used (inches)? 3. A venturi meter is a device that uses a constriction in a flow system to measure the velocity in flow. The figure below illustrates one type of design. If the main pipe section is a standard hydraulic copper tubing having an outside diameter of 80 mm and a wall thickness of 2.5 mm wall thickness, compute the flow rate when the velocity is 4 m/s. Then, for that volume flow rate, specify the required size of the throat section that would make the velocity there at least 15 m/s. Main pipe section 1 Throat section 2 Main pipe section 3 D.
