1. The problem statement, all variables and given/known data A large tank, 25m in height and open at the top, is completely filled with saltwater (density of 1025kg/m^3). A small drain plug witha cross- sectional area of 4.0 x 10^-5 m^2 is located 5 m from the bottom of the tank. a. calculate the force exerted by the water on the plug before the plug breaks b. calculate the speed of the water as it leaves the hole in the side of the tank. c. calculate the volume flow rate of the water from the hole. 3. The attempt at a solution for b i used bernoulli's equation to solve this. P1 + pgy1 + (1/2)pv^2 = P2 + pgy2 + (1/2)pv^3 reduced down to: v = sqr(2gh) v= sqr((2)(9.8)(20)) v is approx 19.8 m/s for c, flow rate = av (4.0 x 10^-5 m^2)(19.8) 7.9196 x 10^-4 for a, f= pa f= 101300 x (4.0 x 10^-5 m^2) this right?
