1. The problem statement, all variables and given/known data A nozzle has a radius of 25mm. Water emerges at the rate of 750L/min. Find the force with which the nozzle must be held. 2. Relevant equations [tex]F = m \times a[/tex] [tex]\Delta m / \Delta t = pAv[/tex] [tex]A_1 \times v_1 = A_2 \times v_2[/tex] [tex]R = vA [/tex] 3. The attempt at a solution I've so far been able to calculate fluid velocity: [tex] v = r/A = 6.366m/s[/tex]. However, finding pressure in order to find force eludes me. I've tried looking into different units, trying the above formulae (but there's always one variable somehow dangling somewhere), and so on. The answer is given to be 79N, so I do know that pressure is equal to about 40000 pascals. This, of course, doesn't help much. Any help is very much appreciated.
