Problem 3: Water flow Consider water [densityr of 1000 kg/ma) flowing through a pipe as shown in the gure. The pipe continues beyond what is shown it is not open to the atmosphere. The gauge pressure at point I (where the pipe 5 u k diameter is 6 cm) is 3'5 kPa, and the water speed '\\ m ' here is 5 mfs. At point 2. which is 2 m higher than point I. the pipe diameter is only 4 cm. mm" Treat water as an ideal uid for this problem. A. What is the absolute pressure at point 1, in units of kPa'? B. What is the speed of the water at point 2'? C. What is the gauge pressure at point 2. in units of kPa
