1. The drinking water needed in an office is supplied in jugs of water. One end of a 0.25 '' diameter plastic hose is inserted into the carboy which is placed on a tall pedestal, while the other end, with a valve to open and close, is held 2 ft below the bottom of the carboy. If the water level in the jug is 1.5 ft when it is full, determine the minimum time it will take to fill an 8 oz (0.00835 ft^3) glass (a) when the jug has just been opened and b) when it is almost empty.
