Ignoring energy losses due to friction, and taking the density of water to be 1000 kg/m³, consider the following two cases: (a) Water flows in a tapered pipe at a rate of 1400 L/min from Point A with cross-sectional area 65 cm² to Point B with cross-sectional area 25 cm² which is 1.5 m higher than A. If the pressure at A is 72 kPa, what is the pressure at B? (b) In another pipe, water flows at a rate of 5500 L/min and the pipe changes from a cross-sectional area of 25 cm² at Point A to 90 cm² at Point B which is 1.5 m higher than A. If the pressure at A is 72 kPa, what is the pressure at B? In Part (a), PÅ < PA whereas in Part (b), PÅ > PÃ. Explain this in terms of energy changes.
