Problem 2. Water is flowing from a hose attached to a water main at 400 kPa (gauge pressure). Stuart places his thumb to cover most of the hose outlet (Figure 1), causing a thin jet of high-speed water to emerge. If the hose is held upward, What is the maximum height that the jet could achieve? Hint. Assume velocities at point 1, and 2 are zero. (water= 1000 Kg/m3 ; g = 10 m/s2 )
