1.)Water flows from a 2 cm diameter pipe, at a speed of 0.35m/sec. How long will it take to fill a 10 liter container?
2.)A horizontal segment of pipe tapers from a cross-sectional area of 50 cm^2 to 0.5 cm^2. The pressure at the larger end of the pipe is 1.2x 10^5 Pa and the speed is 0.04m/sec. What is the pressure at the narrow end of the segment?
