Point 2 is 4.00 m higher than point 1. Point 1 Point 2 Pgauge 15.00x 104 Pa 9.77x 104 Pa u (m/s) 6.00 Velocity Watch out for error when calculating the difference between numbers that are about equal. You may wish to carry several significant figures in your intermediate calculations. Negelect friction and calculate the velocity at point 2. m/s
