3. The figure shows a large uncovered container used to brew beer (0$$) = 1015 ."). The cross-sectional area of the container is 4 /. On one side of the container is a pipe used to take samples of the beer. Attached to the pipe is a pressure gauge. At a given instant of time when the beer level in the container is 2.00 above the pressure gauge, the level of beer in the container is dropping at a rate of 0.2 and the speed of beer past the pressure gauge is 5 . a) What is the flow rate in this beer brewing apparatus? b) Beer flows out of the pipe into a keg of volume 0.66 ". How long does it take to fill up the keg? c) What is the cross-sectional area of the pipe? d) What is the absolute pressure at the position of the gauge in units of Pascals
