1. Water flows upward in a vertical 300 mm pipe at the rate of 0.222 m /s. At a point A in the pipe the pressure is  210 kPa. At B, 4.57 m above A, the diameter is 600 mm, and the lost head A to B equals 1.83 m. What is the  pressure at point B (kPa)?

2. Residents of a certain town are happy because a fountain is to be designed for the park. A nozzle diameter of 50  mm is chosen and the water velocity at the nozzle will be 8.5 m/s. (a) Calculate the height (m) to which the water  will rise. The jet passes through a circular opening 2 m above the nozzle. (b) Calculate the diameter (mm) of the  opening so that the jet just passes through without interference.
