A soft drink (mostly water) flows in a pipe at a beverage plant with a mass flow rate that would fill 220 0.360-L cans per minute. At point 2 in the pipe, the gauge pressure is 155 kPa and the cross-sectional area is 8.00 cm2. At point 1, 1.35 m above point 2, the cross sectional area is 2.00 cm2.(a) Find the mass flow rate.(b) Find the volume flow rate.(c) Find the flow speeds at points 1 and 2.(d) Find the gauge pressure at point 1.
